Aftermarket event and cross-play discussion thread

Short question:

I understand how crossplay-matchmaking works with friends (predefinded-teams)...

But what happens when i solo-queue?

Is it possible that i get teamed-up with PC-Players when i play on console and i solo-queue?

And can i identify on which platform my teammates are playing (when they are not in my friendlist)?

Thx for answer!
