Bug when joining Pace Partner at a junction

Bernie was riding on Volcano Flat and I joined just before the route turns left in the Italian Village. My avatar took a right turn, and I could see Bernie going the same route with me while everyone else was turning left. After a few seconds, Bernie disappeared and I was turned around through the buildings and everything to follow the correct route.

With pedal assist still active I was boosted to 50-60 km/h on the gravel and caught up and sped past the group in no time. I stopped pedaling and still reached the Volcano island before the Bernie group caught up with me…

Both the companion app and the strata activity clearly shows my route taking this strange U-turn at the start.

Everything worked fine after that, but it seems, there’s a problem with choosing the correct turn, if a rider joins a Pace Partner right on a junction…
