Keeps crashing, & says no space

I have iPhone 6 the app keeps crashing within 30 seconds of using the game, no matter what Im doing start a race, change settings it will crash no matter what. Also it keeps saying there is disc full when it wants to save progress in the beginning but I have 30Gb of free space on my iPhone ... Great game but needs these issues fixed so we actually play the game !
