All of a sudden the ability to edit a walk I’ve just done has disappeared? Quite often I forget to switch off the gps after a walk, get in the car and drive for a while, then remember to switch off! So editing the end of the walk is my usual habit. But for some reason it no longer works, try as I might, any number I reduce,just rolls back to the original, and refuses to let me shorten the walk. Any ideas guys?
