Poor upgrade
I loved this app until it upgraded with all the options to purchase new exercises. Now, whenever I try to choose a workout, only a black screen opens. I deleted the app once & reinstalled it (thereby losing ALL of my previous workout history) but after only 3 workouts, the same thing is happening!! I am very unhappy with this app & wonder if anyone else has had this problem?
