Yeah, it must be because of the phone for some reason. Compatibility to the new upgrade, your phone keyboard crashing, memory (ram/storage) issues, or even a virus in your device. Thing is, though, you can’t solve any of this on your own, the tech support should give you some real advice and help you find out exactly what’s wrong here and fix it. For now, only way is fb if you want to chat. If this works, that is. But if it does, it will just confirm the problem to be a device thing.
Also, for some apps, there’s a way to download them on the laptop, too, and play from there. Without fb. All you’ll have to do is check if there’s a pc version.
Oh, and you’re welcome! If anything, I hope this gives you a temporary at the very least solution to the issue.
