Some time ago we had to report issues concerning iBeacons with iOS10. If effected, recording wasn't started reliably or randomly stopped in combination with iBeacons.
We are glad to tell that these problems are now solved with iOS10.3. Tour is now recording smoothly again.
Customers using a bluetooth hands-free kit for phone calls will note that drive log recordings are still stopped during a call. However, this is something that we can solve with a workaround in our Tour app. An update fixing this issue will be available soon.
