I checked the Public Plex 7.31 channel and it’s working as expected.
Another item that 7.34 broke is the theme music. I hadn’t noticed that until I tested the 7.31 and the music kicked in during checking that I noticed it hadn’t been kicking in on 7.34.
Really it just looks like someone accidentally published to Preview early with these obvious bugs and a weekend release without notice. It happens. 
The Preview version used to be pretty solid, even as a beta, and it felt like I was helping improve Plex on Roku by using it and reporting issues. Lately though, reporting bugs with logs and screenshots doesn’t get a response even for beta and replicable issues so ‘contributing’ to Plex feels like wasted effort. Particularly compared to how engaged Plex reps used to be about it.
I’ll just revert back to using the standard Public version, no biggie.
Edit: Roku Release topic edited previous release note to include a comment that this release was for a Roku certification requirement. I’m gonna guess that meant an unscheduled push and since it’s beta the consequences of the bugs weren’t as much of a concern as the certification timing. 
Which happens… not a great look but it happens.
Edit 2: Fixes inbound… thanks for the quick updates.
