GROUPING Tag on MP4 (M4A files)

Has anyone gotten Grouping tags to work on local m4a files?

I’ve tried CONTENTGROUP & GROUPING but neither seems to populate in symfonium is there something else I need to do / try or do I need to make an official request / support entry, just wanted to check before full sending it

You already know the answer :wink:

Fair enough, just uploaded logs & my test file.

I wanted to stop using M4A files completely but SONOS doesn’t want to play nice with OPUS :frowning:
