Updated 2/8/22: NEW issues: FB notices all clump in the ||| Hamburger. Images load slow. ONGOING STILL: FB chats don't alert to new without manual app refresh to check yourself & must be done for every reply exchange. Comments often don't post/vanish or only the first few letters show. Can't upload vids (in app or desktop mode) to chat or a group page. Only to profile status while only in desktop mode. This is a new SG21 too. THESE ISSUES GO BACK TO 2020! YEASH!
