- New version is off
- It won’t let me compare the laps with other friends on the same day. Says lap not similar. Literally same day same track same session.

- Friend integration is currently pretty lacking. When I try to compare laps it complains that the tracks aren't similar enough.
- Worse though is that there's no apparent way of sharing your sessions with friends.
