Unable to connect with EA app and the store

Hello, as the official support never responds, I'm trying to ask you if anyone alse had the same issue and resolved it.
I always had an EA account, never connected with goolge play because my device doesn't have Goggole services, then I insallted it on my main phone (with Google services) always using my EA account login.

Instead I've always benne unable to login into the EA app for PC and into the online shop: same error says I have to login into EA into the game then retry, but I'm already connected with my EA account and never proceed.

Any help, please?
