I recently started reusing the built-in Favorites category again after learning that it provides additional functionality beyond simple grouping (it adds DVR recording priority). However the favorites I established via the web UI aren't consistently syncing across my iOS, iPadOS, and tvOS devices. I've tried blowing away the client installs to no avail.
I can't find a pattern but I can provide screenshots, starting with the web UI, which has the correct favorites selected. Also I'm using 2 HDHR tuners (a 4K & a QUATRO) and screenshots are provided for both to show the inconsistencies. I'm only showing a subset of channels but the problem exists across all channels, including SD.
In addition, favorites selected for streaming sources (Philo via TVE, Pluto, Plex) are syncing just fine. This seems to be isolated to the HDHR devices.
