Thank you for your reply.
Honestly, I have no idea if there's a bug. For all I know I'm doing something wrong because C3 possibly added a new feature and the documentation hasn't been updated, but when I posted that question I didn't get an answer. I just can't figure out how to stop it from happening.
I know I can create an APK and a bundle using the current stable version of the software, but because C3 opened as the unstable version and didn't inform me it was unstable, I now can't open my game in the stable version and I can't create an APK or bundle of my game. Which means I can't update Google play. It's so frustrating.
I have no idea why C3 opened that version. I couldn't tell you how to even get to that version.
I cannot be the only person this has happened to in the history of C3.
Do you know if there is any way of reverting my game back to the current version or am I stuck with it?
Actually 2 things, any idea how I ensure that C3 never randomly opens the unstable version? Maybe is there an unstable version blocker I need to enable in the settings? That would be keen.
(And thanks for listening to my rant.)
