Research direction

Start by reproducing the notification-to-chat flow on Android, using the reported E2E-chat setup and comparing behavior after reopening the app. Trace why messages appear in the chat-list preview but not inside the chat; done means newly received and sent messages consistently appear in the mobile chat without requiring a restart or another client.

Description

🐛 bug type: bug
Describe the Bug

Frequently, new messages are missing. Some times even when sending a message, the chat doesn't show the message that was just sent.
But the biggest issue is when someone else sends a message and clicking the notification, only to land in a chat with no new messages. At that point, going back to chat selection shows the new message as the latest message, in the one-line preview. Clicking it goes back into the chat, where there are still no new messages.

Some notes:

  1. I only use E2E chats on my deployment.
  2. This is happening on multiple android devices with Android 15-17.
  3. The desktop app and webapps do NOT have this issue. Only the android app. I don't have an iOS device to test, but it must be happening there too.
  4. Killing the app and re-opening it before sending a new message when the bug happens, brings the messages back into the chat. If the user facing the bug sends a message before killing the app and restarting, it's impossible to recover them. The only solution is to open the webapp or desktop app.
  5. This has been happening for a while, probably since 7.x rocketchat..
Steps to Reproduce
  1. Click notification
  2. The new messages are missing
Expected Behavior

I expect the messages to show up properly in the mobile chat, like they do on webapp and desktop app.

Messages are missing.
