Something broke today.
When I open the store, the game restarts and enters a reloading loop. I cannot buy anything, nor claim the free gift (sad noises) but at least I can still play normally as long as I don’t click on the store. 
I tried reinstalling but nothing changed.
Same here. White background login screen over and over. Force close it and can use the app for battles but soon as I tap store…dead.
Same here. Store tab crash the game
Daily reset fixed it.
