I clicked on a notification that somebody followed me and no matter where I clicked to after that there was no bottom UI. I noticed this when I swiped to the right to get to the activity stream (after the following notif) and it was gone. Continued to be gone when I clicked on my profile, other peoples profiles, and other bytes I had notifs for. Just left a weird space at the bottom of the screen. Was able to fix it by force quitting the app but I thought I’d let you guys know what happened.
Using iPhone XR latest iOS & latest version of the public app. Hope this is helpful.
