although i use a different mobile client that's built on older code (aliucord for those curious!), i still tried out the new update and it isn't terrible imo. what i mainly don't like is the server list and dms being completely seperate now, how spaced out things are, the swipe to reply feature, the members + pinned messages list being moved, how messages don't have a smooth little transition/animation when you send them. there are some things i like, like how in the members/pinned messages list theres a media and links tab now.. and other things i don't remember right now lol, but the cons outweigh the pros for me.. back to aliucord i go :p
i haven't noticed any activity on my end, but i think it might be cus im only active on like a handful of servers. im thinking the more active you are in more places, or the more active you are in the community, the more likely they'll notice you and stuff, yk? im thinking that's why even though i use 3rd party clients on both pc and mobile, they haven't done anything to my account
