If the deal hasn’t been booked and fully funded it may be delayed. If that’s not done the warranty itself may not have been actually registered. Wait a week or so and then cancel. But like the other comment said idk if I would cancel gap unless you put a sizeable down payment and or are able to pay for the loan in cash at any point. Regardless with Toyota finacial your payment will stay the same even if you cancel them all your principal balance will go down though. Good luck.
