Description:

Recently we've had a constant issue that on both iOS and Android mobile app does not mark any new unread channels as read after visiting them in the mobile client. The situation gets fixed either by closing the app from the history, or clearing its local cache.

Environment Information:

• Rocket.Chat Server Version: 3.6.3
• Rocket.Chat App Version: 4.11 and 4.10
• Device Name: Android and iOS
• OS Version: latest

Steps to reproduce:

1. Go to RC app and sort messages by activity and unread on top.
2. Click any new unread channels under unread list.
3. Go back to channels view
4. Also try marking unread channel as read

Expected behavior:

A read channel should be removed from the list of unread channels

Actual behavior:

A read channel stays under unread channels list

Additional context:

We have noticed this issue with two separate RC server instances / workspaces. Both of them have push notifications disabled, so it might be related to late changes to notification handling on the mobile client.

Other possible triggering factor could be changes in the app to cache more data locally on the client end.
