Live TV - Pausable?

PLEASE DISREGARD - REBOOTING THE ROKU FIXED THE PROBLEM

I have the Plex Server (Version 1.13.2.5154) & Plex Pass. I’m using the HDHomeRun 4-Tuner (HDHR5-4US) and a digital antenna, and it was found instantly by the Plex Server and it’s streaming live TV beautifully.

I’m using Roku Apps (Ultra) to view the live TV, but I can’t pause or rewind the feed. It looks like from the description, time skipping is a feature…what am I doing wrong or what component is limiting that ability?

Thanks
