Problems staying logged in since iOS 10

I have almost 1,200 workouts tracked with the app. Just started having issues. 1) I have to login each time I open the app (never had to do that before). 2) The app (using Facebook) isnt keeping me logged in and will log out midway through a workout so I only get partial tracking. Or weird tracking like all of the time, but only half of the mileage. Please fix!
