I've found a behaviour which doesn't make much sense.
When I complete a ride on my Edge 1030 and synchronise my Marq before uploading the ride, Connect will report intensity minutes. I have to stop the ride on the 1030, open Connect Mobile and manually sync my Marq.
If I upload the ride without syncing my Marq then I will not get a credit for intensity minutes. GC mobile and web will show no intensity minutes at all.
I've tested this several times now and it is repeatable. Feels like a bug to me, is anybody else finding the same??
