I am having a problem where I create a table of uno and wait for players to join. I have a friend that tried to join me after I had created the table and he could not see it listed. Once I recreated it, he was able to join. This has happened a couple times, and the table has usually been open for several minutes. Any suggestions?

That's a known bug already there for a long time. I infortunately don't have any solution at the moment, sorry... I'll post there again when I have news about that.
