PerfectTunes 3.1 Not saving updates to ID Tags

[AdyB]

I have PerfectTunes 3.1 (fully registered) and recently when I update ID Tags, the changes are not being saved. I have an M1 MacBook Pro now running MacOS 13.2 (but I was having this problem before the most recent update).

When I save the changes, the page in PerfectTunes seems to update:

But when I go back in a couple of days later, the updates to Album/Artist & Artwork have disappeared:

My music library is held on a Synology 218+ NAS running Asset UPnP v 7.5.

Change the tags, then close perfecttunes. Then browse by filename and folder, have the changes stuck?

[AdyB]

No.

Then PerfectTUNES does not have access rights to the files (write).

Copy one file to the local computer and try the test again, do the changes stick.

Hi, yes - copying to my local drive and updating the tags from there has worked.

A bit of a long shot but do you have any pointers as to how to how I can reinstate the write access rights to my NAS?

[Spoon]

Specific to the NAS, would be an option within the NAS which accounts have read or write access to a share.
