First, many thanks for a great app! I don’t often buy apps, but this one is well worth the money!
I’ve been looking forward to manage my library with the Grouping tag as I used to in Musicbee.
I have mostly mp3 with ID3v2 tags. I understand there is a confusion in tags used for “Grouping”, so I copied the “TIT1” tag that Musicbee uses into the “GRP1” tag which I understand is the correct tag for grouping. It shows up alright in Navidrome.
However I don’t see any tracks/albums in Symfonium, either via smart playlist or via the Grouping module in the library page.
I’m wondering if maybe I am using an incorrect ID3 field ?
Using the Symfonium latest version on Android 16.
I did clear the tag cache and re-sync. I even completely deleted the provider and re-set it up.
I see a “Custom tag parser” documentation on this support section, but it is not up to date. Googling and ChatGPT are not helping.

Additional information:
Reproduction steps:
Smart filter with “Grouping” = “is present” : empty playlist
Same with “is missing” : all tracks show up.
ID3 tags inspected with mp3tag and musicbee and navidrome show that some tracks do have a “GRP1” tag filled in (ID3v2.3 for those I checked)
