I was able to get the beta app installed to my Mac this morning. When I connected the NEO Bike to the app, the app asked if I'd like to override the settings on the NEO Bike. I selected to keep the existing settings and the app crashed. I don't see any place to get logs for the app to attach here.
After reopening the app, everything seems to be connected and the NEO Bike settings seem to match what I would expect.
