I am the one that originally opened and then reopened this post. I see
that someone changed the title of my topic too cause this was not the
title.I came here today because it changed to light mode yet again. I
see there is a recommended answer now? ...
well it happened again was going for so long staying in dark mode
until today. i walked in and saw it was disconnected from the internet
for some odd reason as all my other devices were online. so i rebooted
it and it came backup in light mode.
