This behavior is quite peculiar. After a certain number of messages, no recent messages appear anymore and all the rest of the messages are just group messages.
What I have tried to solve this-
- Removed site data, deleted cookies
- Removed all extension
- Tried a different browser (Firefox and a chromium browser)
- Used the desktop messenger app
But the problem still persists! It is either some kind of network issue or the problem is with Facebook, because I listed every possible solution.
