Spotube suddenly downloads Opus files

[Patrick010]

I've noticed that Spotube started to download audio tracks in Opus, which is great for quality, but causes a problem. It does not contain any meta data, like when it does in AAC files. Also, if I want to stream them using my Navidrome server the files dont show up because Navidrome cannot extract the needed meta data, what makes it skip the file and therefor doesnt show them in the playlist.

If I inspect the files with ffprobe then I see some interesting differences which make me suspect Spotube not processing the Opus files correctly.

Is there a way to make Spotube download the files in AAC format?
I already set it to M4a
Is this a bug or setting that I missed?

I completely erased Spotube, including residual registry and files and reinstalled. Now it downloads AAC files again.
No idea why it switched to Opus.
