A couple of random ideas based on my today's experience at AutoX:
1) I tried to use "Resolve" while still recording a session (by reviewing my latest run), and I don't think it worked
2) I left the session, opened the summary, tried "Resolve"ing again, and the app crashed
3) I reopened the app, tried "Resolve"ing again, and it took a few seconds. The app felt frozen. Might be useful to show a progress UI.
4) I realized that every time I sync my CAN data to my GPS data, it calculates the exact same offset.
(It's actually pretty impressive that it's so stable.)
I think it would be super useful to be able to add a button like "apply this offset to this device for this session, and all future sessions". Then I won't need to re-sync every session or resume.
