Error when sending encrypted message

[MaxPower654]

Describe the bug

After upgrading to 1.1.15, some android users are unable to send encrypted messages to a room with multiple members.
There is a error message like "Did not sent message, retry?"
Some 1:1 chats were also affected.
After rolling back to v.1.1.12 or using schildi.chat the issue was gone.

To Reproduce

Steps to reproduce the behavior:

1. Send encrypted message to room
2. See error

Expected behavior

I would expect the message to be encrypted and sent.

Screenshots

Smartphone (please complete the following information):

• Device: at least Pixel 4a
• OS: Android 11

Additional context

• 1.1.15 F-Droid and Google Play
• Private Homeserver, v.1.37

From the behaviour, I would expect this issue to be a duplicate from element-hq/element-web#17195, but on android.
I already checked if the encryption event was redacted, but it seems to be fine.

I can confirm I am seeing this issue as well with 1.1.15, I am not longer able to send encrypted messages, but I can from Web or Desktop.

I had two users report this issue to me. they both reinstalled the application from scratch and it resolved the issue. I also have an android device and have not had this issue.

I can confirm that the issue was resolved after clearing cache and storage from Android settings, but it came back shortly after that.

I've hit the same issue today and have heard reports from at least two other people on two different encrypted rooms.

Many people on my server are having this issue. It's happening across many different encrypted rooms.

I've had them uninstall/reinstall & log out and log back in. Both of these work for a while, but the issue comes back.

It's limited to Android 1.1.15. Not happening for any of the people using iOS app, desktop app, or a release before 1.1.15.

I just checked to see if in the rooms that it is happening in had their 'm.room.encryption' events redacted. None of them did. None of the rooms on the server have had the 'm.room.encryption' event redacted.

The bug happens once you logged out from a device:

To reproduce it:

• User A has 2 devices: A1 and A2
• User B has B1 (having User B is probably not mandatory
• A sends messages to a room with B
• A logs out from A2

-> A cannot send messages from A1 anymore

For what it's worth, I did not log out anywhere and still got that persistent error on Android. It just suddenly started yesterday, not even directly connected with an app update.

thanks @pkern. There might be another issue. Can you rageshake mentioning this issue (3792), please?

It is happening even if other users log out. I am preparing a release including the fix.

What is the expected timeline to get this fix onto Google Play? This has crippled my server.
