NextcloudPi folder loading error

Hello all,

I use a “RaspberryPi 4 Model B 8 GB”. It runs “NextcloudPi” with the current V. 1.50.3 or Nextcloud V. 24.0.5.

Now to my problem.
I have several folders and there are several mp3’s. The mp3’s are about 150 MB in size.
If I’m inside a folder and leave it again, Nextcloud loads eternities until I’m back in my homescreen, for example.
This only happens with these folders.
Is there anything you can do about it, or does anyone have the same problem?

Would be really happy if someone has a solution for this.

Best regards
