Over the past week I haven't been able to save any routes via my PC, it just 'hangs' on the saving route screen although I now seem to have dozens of zero-distance routes saved. What's going on? Thanks.
I'm sorry you're having trouble with this. I've checked, and routes are still saving normally from what I can tell. What browser are you using?
One thing that can help is to close down the all browser instances in case some data has gotten corrupted in the process driving one of the tabs or windows.
