Plex TV for Vizio causes unresponsive UI

My Plex for Vizio instances cause the UI to be incredibly unresponsive during the beginning of playback and intermittently throughout playback, seemingly when it is gathering and processing data for playback.

For instance, if i begin a movie or TV show, navigation up until i begin the show and for a brief moment after until the video starts playing. Once it has started playing, i will lose the ability to turn the volume up or down for an unknown amount if time, but it is significant enough that i just forget about it and come back later to adjust the volume (if it lets me). This goes for the plex interface as well, such as changing episodes while the video is playing. This didn’t happen until about i want to say 4 months ago, but its now starting to bother me a significant amount now that we can’t play youtube or netflix all night (comcast data caps).

Does anyone else experience this? I assume the better your TV, the more processing power it will likely have, and the likelihood of experiencing this goes down. This TVs:

E-55 and E-550i-B2, two 55" class Vizios
v2.10.1 of the vizio player
v1.2.7.2987 of the server.

I have the same problems. And I made a post in the Smart TV forums but as yet it’s had no response… https://forums.plex.tv/discussion/241266/vizio-app-extremely-disappointing#latest

Me too on an LG UHD

On my TVs I abandoned the installed Plex app and use Roku 4s. Solved all these strange probs the built in apps seem to have.

Someday, Plex will get Smart TV apps stable and actually work properly.
