(at some point "load more" button disappears)
(pull down, infinite scroll, more messages won't load)
I opened Chrome Developer Tools to see what web requests are sent when I click "load more" button:
Sidenote: reputational risk and lost trust - I am a regular user - I wasn't abusing any functionality. If I was to send 1000 messages a day to all my contact book - I would understand that loading old messages is not working.
I'm actually really frustrated that such a basic functionality is not working.
Maybe I should report this case to FB security as my account is being hacked?
