Update went mostly fine on my Pixel 8 Pro. Cellular data connection with T-Mobile however became unusable after the update and would not function until I used the 'fix connectivity' button in the internet settings. Not sure if it's an upstream bug or not.
However with the new battery indicator, it is now much more difficult for me to see the battery percentage in the status bar, even with increasing the size of the text and display elements system-wide. An option to separate the battery percentage and battery icon would be a great accessibility option.
