However, with your sparse information, I still don’t understand what you expect and what you think is going wrong. You have to provide a little more detailed information. As far as I know, nobody here is clairvoyant.
I have applied .nomedia to a folder on my Nextcloud instance. These exclusions have been reflected when I view my media on the web. However, those excluded items still appear in my media on the mobile version of Nextcloud on iOS Apple iPhone. Is this normal behavior to still see items on mobile applications even though there is a .nomedia present in the directory?
I honestly still have trouble understanding what you mean. .nomedia is not an “application”, it is a marker that serves as an exclusion criterion for some background processes in order not to create thumbnails/preview-images of the files in the folders or to not provide them with a label by AI. Not more.
So what items still apear in the mobile version that do not apear in the web version, the previews or the tags?
Thank you for your commitment. Many people, including myself, use Nextcloud with the integrated Photo App to organize their photos. To view only relevant images in the previews, the .nomedia marker is used. In the mobile app (in my case, Android), there is a Media tab. I and probably helloshaneo assumed that this media tab works the same way as the Photo App of the web version and would like folders with a .nomedia file to be excluded from the preview in the app under the Media tab.
