I updated my Plex Server (Windows) today to 1.16.1.1291.
The EPG only offers me TV channels from another UK TV area. i.e. I’m in the South East of England and I’m being offered Scottish and Northern Irish TV channels.
I deleted the DVR (HDHomerun Connect) and performed a channel refresh with no success.
I then un-installed 1.16.1.1291 and re-installed 1.16.0.1226 and everything was then back to normal - my EPG contained my local TV channels.
