I have a Roku stick 3600X running 8.1.0 - build 4145-24 and Plex 5.3.10. When using Plex, things play fine. No issues.
I also have a two month old Roku stick 3800X running the new 9.0.0 - build 4083-55 and Plex 5.3.10. When using Plex, some things cause the Roku to reboot.
When the Roku 3800X reloads, the enhanced remote frequently (but not always) stops working for up to a minute or two. Then it seems to fix itself and work as expected.
This is consistent and can be duplicated with certain shows. Here's a video of the issue
. Note: after making this recording 2 times (so I wasn't in the shot), the enhanced remote worked immediately after the reboot. In the first recording, the remote didn't start working for approximately 30 seconds, even though I was continuously pressing buttons and standing less than 3 feet from the stick. Battery life was 78% full and TV volume controls worked perfectly.
@RokuShawnS - How do I revert my 3800X from 9.0.0 back to 8.1.0 so things play again? I reported the issue through chat (request #2108808) and support offered to send out a new remote while ignoring my complaint of crashing.
