In my ride today, towards the end I noticed that the large distance display (top-center of the screen) was off by about 0.8km relative to the one next to my name in the Riders Near You display. You can see this in my photos here
Additional photos show that the discrepancy was there pretty early in the ride. I’ll also mention that towards the end of the ride, I started noticing that the XP “ping” and credit was happening when my km counter passed km.8 rather than km.0. Were these Halloween tricks or new bugs?
