Thanks for sending that. I wrote back to you on email. Some apps work on individual files, while others work with directories (and sub-directories). Apps that work with individual files are not affected by this problem because iOS provides the path to the file correctly. It’s the apps (like Nitro) that enumerate directories that have this issue. If you have Photomator, it has a similar ability to work with directories. Is it able to see all of the files inside and also tell when files are added and removed from the directory? When I tried Photomator in the past with a UGreen NAS (which also doesn’t work with Nitro), Photomator has the same problem – pointing to a bug below the app-level.
