Rush games not work due to region not supported.

I'm reaching out regarding an issue preventing me from unlocking the Transfer Market in EA Sports FC 26 Ultimate Team on my Nintendo Switch 2. My region appears to be unsupported, leading to persistent matchmaking failures in Rush Mode, which is required to complete the "On Your Way" objective.
