Ever since I the last update I did on my watch the now playing app won’t let me control Libby which I use for audiobooks. It says now playing at the top then a box under that that says “Apple Watch music” that I can’t click on and then under that is another box that says the title of the book I’m listening to and iPhone and I can’t click on that either.
Maybe that third party app isn't working properly in watchOS 10
