I use the lock screen controls on and off and miss them since the update. As a kind of workaround you may want to check out an app called Sonobit. Sonobit works by swiping from the lock screen to the Today/ Widget screen. You don’t have to unlock the phone and you can play, pause, skip tracks, and change volume. It is an older app that was somewhat popular before locksreen controls became available. I haven’t used it in ages but can confirm it stills works. It looks like it gets regular updates and might work with Apple Watch- can’t confirm because I don’t have one. I am not affiliated with the app maker just looking to help out anyone missing their lock screen controls. I think there might have been one or two other apps that were similar but made by other developers but I never bought them. I will try to find the names and post later.
