Many issues are occurring such as
-audio not working
-mic not working
-SD card not being recognized
-200/400 mhz bug
-docking issues
-reverting the update deleting SD card files from some posts I’ve seen
-some games performing worse or some not working at all
Probably recommend just holding off on this update and wait an update or two. I understand this update comes with the SMT fix and Color Saturation and better gpu performance but these bugs are pretty big negatives.
You can add to the list the fact that in desktop mode, many apps won’t update as the source for the packages can’t be found :(
