Ive been having this issue since buying the game 11 days ago on xbox series s. I have a pc with FC25 with same account name and the season pass works fine.
I have tried multiple different Internets home internet on 4th utility and took xbox to parents as they are with virgin media, a mobile hot-spot using vodafone still I get the sane screen. I've Uninstalled the game, did a hard reset on the xbox, completely wiped xbox and installed again. Followed steps from EA agent about changing nat/internet settings. Added game to router firewall, Tried on external harddrive. Updated all info on ea and unlinked xbox from ea and re added. Same screen Season pass unavailable you will not earn progression towards your season pass. Everything else works fine on the game just no access to season rewards/pass.
On a side note I'm also unable to use the FC HUB on the app as it is locked but all other parts of the app are open.
