Problem with Plex client on Roku Streaming Stick+ and Roku 3.
I’m assuming Plex did an upgrade to v6.7 build3 in the last couple of days. It crashes on the Roku stick during initial loading or when navigating to a program to view and returns to the home menu. Yesterday there was a Roku update to 9.4.0 build 4200-50. Great, all things being equal they should now balance…no such luck it still crashes.
Tried - restart, no effect
- power off restart, no effect
- remove Plex, reboot, add Plex, will not run Plex at all! 
Firestick - It’s all working and that’s just updated too!
LG ‘Smart’ TV - Upgraded this morning to a new Plex app version! Working fine.
Roku 3 - Same issue as Roku Stick. Plex 6.7 b3 won’t run!
