Mileage tracking inaccurate after iOS 11 update – Ride App—automatic ride mapper Review

I’m a daily bike commuter. I’ve used this app for almost a year and loved the way it tracked all my rides... until iOS 11 update and now it shorts my rides by up to a mile each trip. I’ve sent examples to the developer, but still broken. Please fix. UPDATE 4/27/2018: I’ve deleted and reinstalled the latest version today and the app is still not tracking correctly. My rides are reported 1-2 miles LESS than my actual distance. Please fix.
