Store bugged

[Ancient Mariner]

For a few hours i can't access the stores.
When i try to enter both arena and main stores, all i see is a grey empty band (which i guess it's supposed to be the background) and nothing else.
I tried to restart the game, thinking it was just one of the dozens bugs it has, but after that it's still the same :/

Can't buy anything now...anyone having the same issue?

This happened to me yesterday. I had to relog into google store and then went back into game and it was available again.
