I am also having similar issues that others are having. So far:
-Installed the Docker from the App Store
-In the settings I asked it to manually load from one folder, namely /mnt/user/Photos
-When using windows, this "Photos" folder is in the same folder as other things like "flash"
-I put both movies (.mov) and photos (.jpg). For testing I only have one picture and about a dozen movies
-I go to the web UI through unRaid and get to the main page. It says scanning and never changes even after a few hours (12 movies and 1 pic should be quick right?)
-If I stop the scan I just get a simple page that says "Your library is currently empty"
-If I rescan I still get nothing
I've done about a dozen other apps that require media from other folders (Plex, Booksonic, Calibre, etc) with no issues. Any thoughts here? I thought this would be pretty easy but no clue why this won't detect my media in that single folder.
