I have just activated Nextcloud using the webo.cloud service and installed the Android App with the beta version (3.24.0 RC2)
When I activate auto upload of the images folders, it does not do anything, but when I upload individual images via the app they get uploaded and are visible on the nextcloud web page.
I wonder if I can check something why this is not happening, I would expect it to either upload new files or all files depending on the settings.
After waiting over night, the app uploaded the files, so I was just too impatient.
