i have started a ticket with GSA in regards to rooms not appearing on gsa(SFC/OP). apparently this is affecting more than just the OP lobby...at anyrate here is there reply to my latest request,incase others were wondering
Sorry I misunderstood the nature of your problem.
The problem you describe is a current problem with all peer to peer Arcade lobbies. The developers are working to have the problem corrected in the next Arcade patch. I do not know at this time when that will be.
Yours sincerely,
