IOS app major glitch

There is a major glitch on the IOS app which makes playing matches extremely frustrating.  Very often, I will go through a spell where the app will not allow me to send or accept rematches.  This issue has been going on for over a year, and does not change no  matter how many times I update the app.  Please fix this bug; it has been going on for far too long and is severely impeding my experience.

And I should add that this also makes it so that I have to reboot the app to send any game seek.

This is just supremely, supremely frustrating.

sometimes, you cannot rematch on androids too

I get this on Android as well and it makes it impossible trying to play the same opponent or a friend.
