Weird thing. On my last suburban fillup I was informed that the range was off and it would be treated as a missed fill/reset. But over here Suburban (Chevrolet Suburban 1500) | Fuelly , my 4/14/17 fill looks like it should, with mpg and trip distance. That discrepancy can't be intended behavior.
We have already sent an update to Apple to allow users to ignore the missed or partial fuelup suggestions. I expect that the update will reach iTunes in the next day.
You may remove the missed fuelup check in Fuelly. This change will sync with Gas Cubby.
