Not getting rewards.... disappointed – Angry Birds 2 Review

I keep earning rewards but not getting them. I’ve leveled up my slingshot multiple times but it doesn’t register as a feat and I don’t get my rewards. Also many times I’m in the tournament, spent money gems, resources on winning only to freeze at level 5 or 6 and it won’t respond. You lose all your progress when that happens.... really frustrating
