EA ID change lead to not being able to access clubs

After changing my EA ID, updating my email address and password, I can no longer access FC26 Clubs. My EA account is still linked to my PlayStation Network account. Other modes like Ultimate team work correctly, but Clubs fails to connect. I keep getting the "Unable to connect to the EA servers. Please check your internet connection and try again" error when trying to access clubs.

From research it seems like a manual account resync and refresh my pro clubs entitlements should be done by EA - however I have had no luck in getting an agent to assist with this.
