Identified
The issue is within TikTok and it seems to affect only Android 11 devices. The issue consists of the list of notifications (from which the user goes to the editing screen of their post, to actually post the content) not being clickable. iOS does not seem to be affected by it. Pre-Android 11 devices are not guaranteed to work as well.
It's not within our reach to fix this but we are actively involved in notifying TikTok about this problem and waiting for a solution from them.
