I keep getting the error " The game you're attempting to copy is currently not available. Please wait until that game's content is finished being updated." when trying to create a new game. Changing the game's parameters doesn't help. I've had the issue on both chrome and edge, and am not using any pop-up blockers to my knowledge.
Hi Jeremy!
Is this a particularly large game? Some games get so big they cannot be copied (I believe they time out due to the size of the database, but that's a very layman explanation). You can try contacting the dev team through a Help Center Request and they might be able to figure out the actual problem. It's a bit beyond the community level help typically available on the forums.
