Great analysis. Completely agree on the [camera > back to lockscreen swipe changes to video mode….] issue. As they update iOS, it get’s more complex and non user friendly. There is the whole ‘hidden’ shuffle button in the music app etc.
Personally the main annoying part for me is the new control center. When I try to adjust the brightness of the display, I swipe to the ‘music control panel’…. Clearly they didn’t think this through.
