LOGIN DETAILS NOT RECOGNISED

Yesterday (31st May 2026) I could use EA app on my PC quite ok. Today I logged out of the EA app for a which then tried to get back in. I have 3 accounts with EA. Two are old (which I cannot sync with my usual account). I managed to log into these two accounts. However, trying to log into my main account, the one that has all my purchases on, failed no matter what. I have attached a copy of the screen I get. It tells me I do not have an EA account under the email address I was supplying - yet it worked yesterday.

I need this fixed by EA please.
