I used to play Grounded with my kids, but I was the only one able to get into the Public Test Beta--now I can't even play the game with them because they're all on Release and I'm stuck in Public Test. I tried uninstalling and reinstalling... but it's still running in Public Test. 

If there isn't a way to revert to Release build... is there a way to run an older version? They're really upset that I can't play the game with them anymore.

If you are playing on xbox you have to go back into the Insider App and opt out of the test server first. Then Uninstall and reinstall. (Not sure about playing on Steam) Hope that helps.

Hey RevDEAD! We shutdown the Insider Flight yesterday, and the game should update to the release version. Can you please try and reinstall the game if it hasn't automatically updated and put you on the correct version? Please let me know if you're still not able to get on the current version of the game. 

YAY! That fixed the issue. Thanks!
