Controlling workouts on my watch as I used to be able to do

Since my last Apple Watch and iPhone updates, I can no longer use my watch to start a walking workout. Nor can I end my workout by swiping my watch face to the right as I have always done. Apparently, I now have to start my walking workout on my iPhone and end it there was well. IMO this is not progress!

Currently, my watch is "paused" after this morning's walk, and I can't unpause it either on my watch or my phone. Any help unravelling this would be greatly appreciated!
