I'm unable to access Shop since 2.1.0. It just stays in loading forever. Can you advise?
Edit: Ok, I found a way.
I enabled apps related to Google Services in the Apps section in Settings. Updated them all (including the google services one Fire Emblem kept nagging me about) and I could access the shop.
Maybe this causes 803-3001 but in that case I can have two separate memu instances in multi-memu. One for playing without interruptions and the other for accessing shop. During my short gameplay test the error 803-3001 did not occur.
