1. * * * I would like to know how the integration of coturn into Delta Chat is progressing, so that it can work with any account ā€” whether a regular email account or a self-hosted chatmail server (although it may not be necessary there, perhaps as a fallback). 2. I would also like to know how the implementation of the ability to use (connect) a custom coturn server in the application is progressing. 3. Which coturn server is recommended for self-hosting? ---

Hello. The day before yesterday, a friend of mine lost the handset button in the chat. When I tries to call him, he only sees a missed call. The Debug Calls mode is turned on and until the day before yesterday everything was fine, calls went through, the handset was in the chat. Today, Delta Chat was even deliberately removed and reinstalled, but the handset never appeared in the chat. Latest version of Delta Chat. Please tell me what could be the problem? ---

I rolled back to the previous version (2.43) - calls started working. Looks like new calls require Android 8 or higher ---

I have a test profile with two relays. One of those now seems offline. The profile is still able to send and receive msg from the other relay, but the header shows with yellow dot and Connecting.. Is this normal behaviour? ![IMG_20260328_101432](https://support.delta.chat/uploads/default/original/2X/3/3a672900c178c7d9a23f32a7691ff26dd0c2753a.jpeg) ---

What does the connectivity view display? Maybe there are multiple relays and one of them is not working? ---

A user on android 6 and dc 1.58.4 says that because contacts upgraded to 2.47 , there is now lots of garbage messages, wrong assignation of chats etc Their messages: > āš  Donā€™t update to Delta Chat \*\*v2.47.0\*\* ā€“ it is buggy! > After an aquaintance updated 4 days ago i have got a big amount of broken chats, undecrypted garbage messages, and messages from group chats moved into dialog chats. > It is coming from many contacts, probably who also updated. > > I had read the blog and the new description of release in GitHub, and i found no suspicious changelog record. Probably, the developers did not know yet that the v2.47.0 is harmful to ecosystem. > > BTW, i stay on ArcaneChat 1.58.4. > 1.58.4 is old version, but it should not be called \*extremely\* old as it released just less than 1 year ago šŸ˜‰ > I did not like some little new feature of version 2. That is why i intentionally reluctant to update. > I should not expect breakage if in changelog is not said ā€œthis is the last version compatible with version 1.x.x.ā€ If it is not Alfa, Beta or version 0.x.x. > One year is really short age. Many other software continue to work unupdated with much lesser breaks. > Probably, i will be forced to update šŸ˜§ But the problem is not in my old enough good client, but problem is in other new unreliable clients! V2.43.9, v2.35.0 and many other 2.x.x worked enough reliable with my client ā€“ only the most recent release broke most E2EE chats. > Would be better for ecosystem if all people stop updating after v.2.43.9 (the last reliable) and donā€™t inflict sudden information loss and donā€™t force me to update. ---

Yes thatā€™s correct. But being auto relay switching enabled, why display something that normies would worry about? Average user (my mum šŸ¤—) would just think itā€™s Delta Chat is broken, and would not go deep into menu and sub menu to find out one of the relay is down. Thatā€™s just tech stuff normies donā€™t want and probably donā€™t need to know about. ---

When there is an incoming call, I do not see the window to accept/reject the call. Only in chat it is displayed as a missed call. When making an outgoing call, the window appears normally. Iā€™ve changed various settings/notifications in Android, but nothing helps. Please tell me what could be the problem and how to find the reason for this behavior? This was also in version 2.43, and remains in version 2.47 ---

if will take some more days. in general, we roll out slowly - so if issues pop up, they affect as few people as possible. if you want to test and use 2.47 today, use one of the other options ---

I had a message order problem on one of the two equipments. On the equipment (Windows desktop) I replyed, the message order is ok. On the other equipment (Android) the message order is vice versa. Message 1 send date by another person: 10:28:09 via [nine.testrun.org](http://nine.testrun.org) Desktop: Message 1 received on Windows Desktop: 10:28:09 from [nine.testrun.org](http://nine.testrun.org). Same time as the send time from the sender. Message 2 send by me as response on Windows Desktop: 10:28:53 via [nine.testrun.org](http://nine.testrun.org), tarpit.fun, chat.in-the.eu. Display order: Message 1, Message 2. Order of the two messages is ok on Desktop. Android: Message 1 received on Android: 10:30:59 from [nine.testrun.org](http://nine.testrun.org). Message 2 showing send date on Android: 10:28:53 (same as on Desktop). Display order: Message 2, Message 1 on Android.

Today I tested calls on a Huawei P40 Lite without Google services, Android 10, and on a Xiaomi 10T, Android 13, with Google services. So, the first one showed the incoming call screen, while the second one did not. After several attempts, the first one started throwing an error as if the session hadnā€™t been completed, and after that, its WebView malfunctioned ā€” everything on the Huawei just crashed. Videos wouldnā€™t play in browsers, and in other messengers, the call audio functionality stopped working. This was resolved by rebooting the device. On the second device, aside from the incoming call screen never appearing, there were no issues with the Google WebView ![Screenshot_20260401_162338_com.b44t.messenger](https://support.delta.chat/uploads/default/original/2X/0/010b157dfb704924601b960f537e91818d31b97e.jpeg) ![Screenshot_20260401_162312_com.android.systemui](https://support.delta.chat/uploads/default/original/2X/d/d4a0e6445b4c1d769b58c3b56e92d613aee09527.jpeg) [deltachat-log-20260402-000918.txt](https://forum.delta.chat/uploads/short-url/pyo8dgcPnhJEUm6hwptbC3cX2Ad.txt) (4.6 KB) ---
