Did anyone figure this out? I am on Xbox and it just continues to say I am offline not joinable

I just bought the series s and have the exact same problem, can't join friends and says in not joinable and offline, although I have crossplay on.

I have the same issue

This is in no way isolated. Tons of people having this same issue. Including myself.

I just wish they would figure out what is going on and fix it

Same. I have cross play on and can’t even add friends… it keeps telling me I’m offline not joinable it’s aggravating

I just solved it, I made the transition from ps to Xbox and in my ps account was selected crossplay off, just switched to crossplay on and restarted the Xbox, still offline but now can play, join and invite my friends. Hope this helps!
