Last weekend I was on a ride with multiple stops. Was using a route created using MyDrive website. But had to abandon TomTom app and switch to Harley-Davidson app in the middle of the ride after a big detour. TomTom currently doesn't show waypoints/stops for MyDrive routes. So there's no way to delete or mark as visited one of them.
I'm sure there are many reasons to use multi-stop routes, but I hope TomTom won't be ignoring the needs of motorcycle riders with iPhones for long.
