IOS sync creates subfolders but not actually uploading the images

Tested on Iphone 12 and 7. Running latest IOS app and nextcloudpi running nc 20.0.4.

The app creates the subfolders, Year/Month style. So far so good, but it doesn’t actually upload any photos. Also calDAV and CardDAV doesn’t work?

On my android phone everything runs perfectly fine, I don’t understand what the problem is.
