It seems that some people, even despite being accepted to BF6 Early Access, can’t join any mode except Training Range or can’t use their EA Play Pro pass.

While everyone can play the Battlefield 6 open beta, there is an early access period that has gone live right now, but you can only access this if: You signed up to Battlefield Labs before July 31, then log in with the EA Account you registered with.

The second way that codes were given out for the Battlefield 6 early access beta is via Twitch Drops. Those who watched streamers playing Battlefield 6 during the reveal livestream last week would receive a code to redeem on the Battlefield site, which would then give them access to the beta on August 7 instead of August 9.
