1st try: uploaded music, created https://open.audio/channels/pulverdingen9/ on the fly, right shows all titles greyed out with rotating circle. No album info, no corer art.
Next try (maybe my metainfo was garbled): deleted pulverdingen9. recreated it, doesn't work - it's already taken.
So added pulverdingen_9 without uploading MP3 - Same problem: right side of https://open.audio/channels/pulverdingen_9/ greyed out.
Looked up https://docs.funkwhale.audio/users/channels.html, didn't help.
Disabled uBlock Origin, didn't help.
Tried in Firefox, didn't help.
looks like I have that problem on channels created by others, too.
