Missing random files from WebDAV media provider

Issue description:

I’m using Symfonium for several years now (on my Google Pixel 7), and I’m very happy with it, and I’m using it also for my radio recordings. But since the update to 14.0.0, suddenly some files from my WebDAV media provider are not appearing after syncing. For you to reproduce it, I’ve set up a (temporary) dedicated public WebDAV server (without credentials), with some mp3files I’ve produced by myself (but for this purpose limited to 5 minutes per episode instead of the regular 1-hour) so you can experience it yourselves. The address of this WebDAV server is https://webdav.zwanevlot.nl, and you can also just download the files for research purposes.
On this WebDAV server there are 11 mp3-files (recorded 5 minutes every hour, from 9:00 untill 19:00 today), but only 7 of them show up in Symfonium’s album page, see screenshot 1.

However, when I go to “Files”, and then choose the WebDAV media provider, then all 11 files are visible (see 2nd screenshot). And when I choose a file which is not visible in the album page, then it can be played, but the ID3 tags are not shown properly, only the cover art and the file name is shown then.

And when I copy the files to my phone and choose local device as media provider, then all 11 files show up correctly, also with the correct ID3 tags, without any issue.

Now I have two questions:

  1. Can you solve this in the next update?
  2. Can I somehow downgrade Symfonium to a previous version (13.x) until this problem is solved (can I download it somewhere)?

(I know there was already a report made for this issue by a user called ‘ceres’, but this one so brief that I opened this new issue anyway)
