iPhone 7+ user. – Billy Blanks Tae Bo Fitness Review

I have lost a lot of weight cause of Billy Blanks. And that’s just from the basics. When I found this app, I was excited and got it. Unfortunately, it seems to crash a lot with my iPhone and it won’t save to my stacks. They disappear from there and it won’t let me re-add the videos to it. The + (plus) sign does not function and won’t do nothing to add to the stack.
