Annoying constant popups.... Every time I open the app I get a massive full screen popup asking me to join a school, I know, I've known for months, it's obnoxious! Can you not have a "don't show me again" checkmark? It makes me hate using this app because I have to get thrown out of my conversation to get ads about school when I'm 24 and graduated years ago. And "did you know you can screen share?" Every time I enter a call. YES I DID you told me 10000 times, every time I join a call! Popups!!!!
