ios 16 workout app

When out for a run and using the workout app, I used to (before IOS 16) be able to swipe left to control my music or podcast (skip songs or fast forward through podcast commercials) but now when I swipe left I get a "Music" screen but it is not controlling what is playing on my phone (as it used to). Also, there is a little yellow circle right beside the time field at the top right side of the watch screen. Any idea how I can get back to the IOS 15 behavior??

Second question - I no longer see a way to change the data fields that appear in the workout screens as I had been able to before. For example, I would like the "walking" workout screen to include "Elevation gain" which is not there by default. Not sure if that is an IOS or a WatchOS controlled feature?? Ideas??
