FC 27 Lite Triggers "Feature Disabled" on Web/Companion App

Yes.

Solution that worked for me:

1. Refunded FC 27 Lite on the PlayStation Store (even though it’s free).
2. Deleted all FC 27 and FC 27 Lite data from the console.
3. Restored Licenses (Settings → Users and Accounts → Other → Restore Licenses).
4. Got the EA Play trial back.
5. Still couldn’t enter Ultimate Team on FC 27 (got the “high volume of server traffic” error only on my account).
6. Launched FC 26, played one Rivals match, then fully closed the application.
7. After that, the FC 27 Web App and Companion App features (Transfer Market, SBCs, Evolutions, etc.) came back and started working normally.

Hope this helps someone with the same issue.
