The most particular case: I have 2 jails: one with transmission, the other with servarr (radarr). I mount the same network share in those two as /mnt/downloads, so Tranmission can download and then radarr process. Since it's jail, I have "transmission" in transmission jail in wheel, and "radarr" in radarr as wheel. So, in theory - full access. But it's a jail.

Now, if radarr just uses transmission it all works. After the download if finished, radarr can move the file to another location.

But if radarr sends tags to transmission, and the file will be saved in /mnt/downloads/radarr, transmission works fine but then radarr user has no permission to access that file.

I removed the tag and it works, but I have no idea why it doesn't work.
