I had installed the 3.37 beta (?) a few days ago and tagged some albums with it. Now I have version 3.37, and all the tags are gone in Mp3Tag.
MediaInfo: Tags are there
iTunes: Tags are there
MPC-BE: Tags are there
When I go to “Advanced Tags” in Mp3Tag, the tags aren’t listed there either. However, there are 4 tags that definitely weren’t there before: MP3GAIN_MINMAX, MP3GAIN_UNDO, REPLAYGAIN_TRACK_GAIN, and REPLAYGAIN_TRACK_PEAK
It seems to only affect tags created with the latest beta. Slightly older tags—and, of course, all those from before version 3.37—are still there.
When I create a new tag in iTunes, it doesn’t show up in Mp3Tag either.
I haven’t changed anything in Mp3Tag’s since years ;). It’s supposed to write ID3v2 and APEv2. When I check this with file *.mp3 (wsl2)—it matches—and MP3Tag also says that ID3v2.3 and APEv2 are included.
