PLEASE UPDATE! – Tony the Truck and Construction Vehicles Review

My 2yo has loved this app for a long time, I even paid to unlock all of the other trucks. But now since iOS11 it won’t even let him open the app anymore, and I can’t find a way to contact the developer. I’d give this a 5 star review if they would just update it already!
