I now have PMS v1.25.3.5448 with the latest hotfix for Shield v9.0.1(33.1.0.274) finally running stable for almost 2 days.
Issue for me was I had to format my external USB SSD disk with MSDos fat32.
Then cleared all app data of the Plex Media Server app on my Shield and setup everything again and then setup PMS to use my external USB SSD for storage in the Plex Media Player.
Then:
- Stop PMS server
- Eject my external usb drive from Shield
- Connect SSD to my MacBook Pro
- Copy my Plex backup to the /Android/data/com.plexapp.mediaserver.smb/
- Connect SSD back to my Shield
- Start PMS server again and wait a few minutes to let everything sync and startup
- And finally pin back al my libraries so they will be visible again in Home Screen
This way I can use my Plex normal again.
Only issues which need to be fixed (for me at least) are:
Support for using NTFS or exFAT again.
Ability to access all /Android/data/* folders on my external usb SSD over the network again (SMB share)
