as far as i know and experience, this is the only app with the greatest and many bugs in it, it has the biggest bug ever. Imagine you're in a video call, you click the back button and then boom your video call got stucked you can't click it, you can't maximize it and the only thing you can do is restart your phone and call again to fix it. I've been experiencing this bug for 3years I've been quiet enough for 3years Hope y'all fix this, stop those nonsense update and fix your bugs.
