Not understanding assignment of SSD Cache ownership or directory and file permissions

When I create a new file on the array and it is cached to an SSD pool the UnRaid assigned directory permissions appears to cause operation to fail. This happens when downloading a video file using Windows Brave browser and from a script running on a Linux VM that mounts the array. It happens on youtube and other video sites. 100% consistent.

Likely a configuration issue but as a new user the firehose of information is a bit overwhelming. Need help please.

Example:

Directory automatically created in cache /mnt/ssd/Pool/Video/Blog/
    drwxrwx---+ 1 nobody users  194 Sep 23 16:43 GamersNexus.[2020]/

Partial video file downloaded from youtube into /mnt/ssd/Pool/Video/Blog/GamersNexus.[2020]. Finalization fails to delete the partial webm part file and also assemble the final mkv file from the parts.

Other failure case is when downloading video file with Brave browser.

Changing permissions of the UnRaid created /mnt/ssd/Pool/Video/Blog/GamersNexus.[2020] directory with chmod a+=rwx fixes the issue for subsequent downloads. All newly cached directories have the same issue until I manually change the permissions in the SSD cache.
