Board Game Arena

Hi, I find that when I start an Heat Arena real time game, and whilst waiting for players to join if I take a turn or two of my turn based games, I come back to find it cancelled. Is this correct functionality?

It doesn't always happen.

Are you looking at the Heat game / any BGA page on another tab or do you leave the page? If you leave it, perhaps the table fills up and starts waiting for you to accept, and someone cancels because you don't show up?

It's one tab.
Arena games seem to automatically start, right, rather than needing to accept like in Play. The turn based game I play the most is Azul, so I'm only away for seconds generally and keep my eye on the green table icon.

Sorry, I missed that you said Arena. Then I don't know what it could be.
