The Continuous Riding feature now is now announced as the big new thing when I open the (production) Windows TDA. I tried it today (again, in the production TDA), and was rather disappointed. The very first transition that I was to experience did not happen. Instead I got a message saying "the next course cannot be loaded due to technical issues". No further explanation. I continued the playlist anyway, and on the next transition it did work, and rather smoothly too. But the title of the ride on top of the window did not change (I do not ride in full screen mode), that stayed identical to the previous video. Also, it uploaded with just the first title, and no indication at all about the title of the next (attached) ride(s).
Then when it uploads, it appears as a long straight line between the two locations (in my case the UK and Switzerland), which is completely lame. Obviously, it should have displayed as two separate unconnected rides. In this way, this is only going to be useful for multi-stage rides that are continuous to begin with. And even then, we need a playlist, which is beyond our individual control.
I think this thing went from beta to production almost momentarily. It would have deserved a bit more extensive testing. I don't think I will use it much.
