Buffering Problem on Roku app

Server Version#: 4.147.1
Player Version

When I play a TV show on the Plex app on my Roku, there is a buffering problem, where the show freezes, and I have to rewind 10 seconds and restart. It just happens at random. When I check the connection in Roku settings, it says the connection is good. The buffering problem doesn’t happen in the other apps on the Roku, only the Plex app.

Any suggestions on how to get around the buffering problem?

Oops! I had the server version wrong. It is Mac server version 1.43.0.10492.
