Hi, I had the same problem. I solved it by opening the app and deselecting the option / closing the app / relaunching the app /selecting the option / exiting the app. And then it worked. I can't explain why so you have to follow my magic formula. Maybe someone will demystify the bug or find a shorter workaround. Nevertheless this solution will help you right now. And who knows when someone will deign to answer? HTH
