This is honestly just people hating it because its different? There is no feature removal, its just built differently. Also i find it disgusting that THIS is why people are boycotting nitro. Imagine being comfortable supporting probably the largest service hosting CSAM (and not doing much about it) but drawing the line at it taking an extra tap to view server members.
I mean they've broken the app for me. After about 15 minutes the message window won't refresh regardless if I change channels or servers. Notifications take me nowhere so I need to go find the event myself. I'm only a light user so I'm sure there is more. It's not just because it's different, I actually like the new UI better.
