[Reported] Watch Ads is Broken

Platform, device version and operating system:
Samsung Galaxy S21+, Android 11.0
Screenshot or image:

What you were expecting to happen, and what actually happened:
Selecting “watch ad” should make an ad available to watch.

How often does this happen? When did it begin happening?
It’s happened for at least 6 months now. Usually restarting the game will fix it. I tried 3 restarts to no avail. But like most things in Gems of War when they break… clearing the Cache finally made it so I could watch the ad.

Steps to make it happen again

It’s annoying though when it happens.
