The new route progress bar is great, helpful, and a nice bit of feedback to indicate that you finished a route. (nice when you have already done the route and gotten the badge)
Not sure how many small errors there might be, but thought I would post here.
My understanding is that routes start and finish at a banner, so sometimes there is a lead - in.
Just rode the Greatest London Flat route and the lead-in distance seems wrong to me, there was no banner to indicate the “start” of the route, and there was an obvious banner at the finish that I am pretty sure should have been where the lead - in ended.
