Attacking the Clock Racing review for Facebook & Instagram

App is great when it works. However, for some reason, the Facebook app has disconnected my site and will not let me reconnect my account. Even though I type in my password and it directs to Facebook, it still says to reconnect. I can still see my shop with products on my FB/IG pages but I cannot utilize any of the functions to create ads with the products. I need assistance, please.
