Groove couldn't recognize tags of flac files after writing from 3.06a and shows "Unknown album", "Unknown artist" with no song title. If I write tags through Properties->Detail then everything is fine. Besides, when I tried Properties->Details->Remove properties and personal information->Create a copy with all possible properties removed on an edited flac file, I received an error implies tags had been corrupted, and I could only remove tags in mp3tag. Issue never happens in the previous version
OS: Win10 build 21337
The current MP3tag version is 3.06h.
If Groove music has such a spurious support of flac files like WMP has, then perhaps this thread is of interest for you:
