Hi VanZet,
I just always make sure that all files are already on the hard drive so that they are recognized and assigned correctly.
If I add something new and it is recognized incorrectly, I edit the file until it is recognized correctly.
This means I can delete my media libraries and have them recreated at any time.
I love my Nvidia Shield TV Pro 2019 and my Plex Media Server on it.
If you want, you can Backup and Restore your Database!

With the Nvidia Shield you have the advantage of having servers and players on one device, meaning that films can be played in direct play without a LAN and almost never have to be transcoded.
If you want a different server, it may have to trancode and cannot play one or another file in Direct Play.
Therefore, the best server is still the Windows or Linux server, with a strong processor and a good graphics card that can transcode 4K HDR with TrueHD Atmos Sound or DTS:X.
The currently best NAS devices are Synology and Qnap.
Synology acts similarly to Apple and Qnap acts like Android.
If you want to add additional hard drives via USB, both providers do not offer support.
However, Qnap has its own extensions that are only connected via USB.
Synology, on the other hand, offers extensions via SATA connection.
The basic devices are available with 2-6 hard drive slots; with Synology you can tell from the first number how many hard drives this can be expanded to.
The DS224+ has 2 slots and cannot be expanded, for example.
The DS723+ has 2 slots, but can be expanded to 7 slots with the DX517.
With the TL-D800C, Qnap has an expansion of 8 hard drives via USB connection. I therefore assume that external USB hard drives can be used via a hub without any problems.
As a basic device I would use the TS-264 from Qnap.
Ultimately, you are in good hands with your Nvidia Shield.
And VanZet, here the Pin has help and solved the problem.
