I'm syncing my pictures and documents folders to dropbox via backup (windows 11). I want to make a few large folders in pictures to be online only as i don't use them much so don't need them taking space on my local drive. However, when i select a folder and do dropbox > make online-only, it does absolutely nothing. it starts syncing, the icons on the files briefly change from the green tick to grey cloud but after a while, everything is back to being green. all the files are still available locally and has no effect on the disk space.
This feature used to work fine but seems to completely broken.
