Glitching ads keeping game from progressing – Gold and Goblins: Idle Games Review

I keep trying to play, but every time I try to open a gift barrel by watching an ad, I get a black screen and no ad. I have to force close the app and get no reward and the gift barrel does not open. The game won’t give you a second gift barrel until the first disappears, so I’m just stuck. Very frustrating.
