Hello, hope this finds you well.

I use two PCs and two different licenses, one is Studio 2019 and the other is 2021.

I tried to import a very small sdlxliff file to an empty translation memory with 2021 because client asked to export them to tmx,

but had error with message "this file can't be imported."  please find screenshot.

Importing translated file to TM on 2019 from 2021 still works - that is older one is always better and the new one does not work.

I also have trouble finding files that are added to project with Studio 2019 on 2021,

When you add file with 2019 the file can not be seen on file list on 2021.

I believe there should be a backward compatibility because they are close versions, only three years but it seems they don't. I appreciate your ideas, thanks!
