I posted a similar message on General Discussion a week ago. The bug continues:
I rode a 103 km meetup, round and round the volcano today. No powerups, and the lap counter was blank. This was not on a TT bike. Other riders in the meetup report the same.
The good news is that when the meetup was over, there was still a km to go to get to the finish of the 25 laps, and as I approached the finish, the lap counter was showing 24, and switched to 25 as I passed under the arch. I also got the badges I was after.
But this is a repeatable problem. I like powerups!
