Live TV > Browse (to the right of DVR Schedule) has stopped working, saying “Something Went Wrong. An unexpected error occurred.” I’ve used this feature a lot; it used to work.
This is corrected in the current beta version, 1.42.0.9975. You appear to have a Plex Pass subscription so you can upgrade to that, or you can wait for the next public release that contains the fix.
