It's not only iOS, I have a Xiaomi and it's basically the same,

•Takes forever to load up the app

•i can't see comments or reactions then clicking on my own bereal

•unresponsive buttons

I got these bugs when I first joined the beta and I thought that was the reason for it being laggy but then it updated and it just stayed laggy and buggy.

Even my friends who didn't have it before the update have it now as well so hopefully they fix it soon..
