Problems with ID working on different OS - Catalina an Big Sur

[Else-Britt]

If I open an ID-file made in the last version on a Mac-Catalina platform, it's not possible to change it and/ or save it on a machine with BigSur, even if it's using the same version of ID.

Have anyone had the same problem?

What version of InDesign are you using (exactly)? What happens when you try to open the file you're having problem with? If there is a message, what is it?

There should be no problem opening a file which has the same or earlier version on a different operating system.
