However, each new version requires us to set the same values again. Is this a known issue, and are there any known workarounds?
It is not a bug, it is a design decision, to force to update subtitle for each new version of an app.
If that's a problem, file a bug report for enhancement request.
Workaround is not to forget to re enter subtitles.
Note: I've found a good practice: I created a text document with all the fields required in AppStore Connect, with entries in any language. I have all information in one place.
I update this file with new entries for the new release.
Doing so, less risk to forget something ; and I can copy and paste from text file to AppStore Connect.
