Hidden files still appear in iOS Media tab after disabling "show hidden files" in the App

Hello,

I’m running Nextcloud on a Raspberry Pi and recently changed my configuration to allow uploading and syncing files/folders starting with a dot (.) by setting:

'dot_files' => true,

This worked as expected — I can now upload and sync hidden files/folders (e.g. .hiddenFolder or .secret.jpg).

However, I now have a problem:
These “hidden” files still appear in the Media tab of the iOS Nextcloud app. This is what I want to avoid because why else would I have the option to “show hidden files”?

Questions:

  1. Is this expected behavior of the iOS app?
  2. If the answer from 1. is no, how can I properly set it up to not show up in the media tab?

Any help or suggestions would be greatly appreciated.

Thanks in advance!
