Hello. I was under the impress that by sharing a Read only secret of a file, that files will be synced but any changes wouldn't be sent over after syncing? This is my set up: Folder on PC (with photos) Copy the Read Only secret -> Folder on my NAS (set up pasting in the read only secret). Now if I paste a photo in the NAS folder, it won't sync back which is correct. If I place them in my PC folder, they sync over, which is great. However, when I delete the photo's from my PC's folder, they are also deleted in the NAS folder. Is this an error, or a limitation with the software/not what it was meant to do. I basically just want to automatically backup this specific folder, and then to save space delete its contents every now and again, knowing they are safely stored on my NAS.
