You took the good things about this app and broke all of them. It's become almost unusable. Chat 'bubbles' or 'heads' or what ever name you change them to next will disappear in the overlay of the screen. I will have to reopen the app and reopen every conversation individually because I can no longer select previous conversations from the bubble. The recent conversation cache clears out and is vastly inaccurate. The screen overlay fails and won't display. Edit2/4/22 app now will not open at all!
