Are you working on Windows? And sometimes you say you can open an V22.2 saved model on a V22.1.2 version?
I’m working on Mac (M1-version), and model saved in V22.2 can NEVER be opened in V22.1.2 again, even if there was NO modification in the file other than opening and saving in V22.2.
I understand that there must be file format changes sometimes. But if there is a backward incompability, it would be good practice to alert users before they destroy backward compability!
