Unable to access the FC 26 Web App for over a month (Login Unavailable message)

Hello everyone,

I’ve been unable to access the FC 26 Web App for over a month now.  
Every time I try to log in, I get this message:

“Login Unavailable  
We're currently having trouble with login services. While we work on it, you can try to log in from your Console or PC to get the full Football Ultimate Team experience.”

I can play FC 26 normally on PC (Steam) — buy, sell players, and play Ultimate Team matches with no issues.  
However, I still can’t log in to the Web App or Companion App from any browser or device.

I already contacted EA Support and Terms of Service, but they said it’s not related to any restriction or ban.  
It’s been more than a month and I still have no access.

Could this be a system flag related to my account from FC 25, or some region/IP issue?  
Any help or update from the EA team would be appreciated.

Thank you,
