Крутые птички

this is a test app for payment testing only. it doesn't impersonate any game since Bravo Birds and Крутые птички are also our application on this same developer account. We are just having problem with payments, for some reason we get "authentication is required. you need to sign in to your google account" error every time we try to initiate the purchase. Original app (com.datcroft.bravobirds) doesn't have this issue, but new one (com.datcroft.bravobirds.ru) does, and so it seems to be about this app. maybe it has something to do with the recent app block we had for impersonating. could it affect our merchant account? that would be great if you could check it and provide some advice
