So my excitement for a successful upgrade is gone. I went to watch a video only to find I have no media player, I installed Celluloid only to find that playback was slow and in black and white. (This is what I got from the system repositories). (Also it didn't honor my theme settings)
I installed the flakpak for Celluloid - and that worked, And it sort of honored my theme settings (meaning I had to turn off dark mode, but at least I could)
