In the latest log I ve seen you have done changes to the GUI (sidebar). One of those changes was to remove the background color of the menus header? Or did you just move this option to the settings? Couldn’t find it. :-/
Even my wife told me, that she’d want it back because now UI is very dark (on dark theme) and the color (depending on the system) helped great to know with which Kodi you are connected.
We use several systems in different rooms, like living room, kids room, sleeping room etc. So, if Yatse header was shinning in blue, I instantly knew that I was connected to Living room.
