[SOLVED] Musicbrainz Picard - again.

[qroft]

[SOLUTION] Take a rest and sleep! I have been up now for nearly 15 hours and only after like 4 hours of trying to find the error i must admit that i suck - a lot!
I did not saw all tags because i had the setTagsToRead filter on - sorry for that and thanks for your support

I have found an issue from 2017 and i have a strange situation with that post.
So i created an mp3 and custom tags like "Publisher" and "License" to it with Musicbrainz Picard.

The above mentioned post contains an answer with two codepen examples.
When i load my mp3 into the first one, it does not work.
When i load my mp3 into the second codepen example, all looks fine.
In short this means: the console shows the tags.tags.TXXX content.

But when i upload the mp3 to my own server, it only shows the standard tags without the TXXX ones.
For me this means that something is wrong with my server, but what?
I just upgraded to PHP 8.3 but that is absolutly no reason to be the reason.
If i load the mp3 into MB-Picard, all the tags are there, also the custom ones.

So could you show an updated codepen or example on how this should be working?
Thanks a lot for your time and greetings from this corner of the planet.
