Do you have access now ? I'm facing the same problem, I thought it would've been resolved this morning after receiving the message that trade on the go was available on companion and Web app but for some reason it still isn't.
I've seen some posts on Reddit which says that apparently companion doesn't register Switch 2 users as players in the database - meaning they don't register the time you play and therefore won't be able to unlock the companion access to transfer market - which would be very unpleasant @ea_staff
I finally got access after playing 5 days in a row, each day at least 3 games and completing the weekly reward in rivals. I got the tip to play many different game modes in ultimate team.
The message “trade on the go” is a very confusing message as it doesn’t unlock anything.
