I have noticed a few times when SD fails to record a flight. Today flying on a 2.8 hours training flight both my Instructors and my SD simply didn't show any track when we landed, despite the flight timers running, and the aircraft showing in the correct position on the airfield.

My instructor also said he saw the line being created on his device during flight - he had it out, mine was in a door pocket, but when both stopped nothing was recorded on either device.

under what circumstances does SD NOT record? Both running Iphones on the latest ios. do we have any debugging or logs we could check?

Several times, and most of the time it seems to work. I initially thought it was due to the fact I was engine on/off blocks and then going off to fuel, being on the ground for a while before taking off, but the last flight my instructor saw the track in flight, then when we landed he had no track, for me when i checked it on the ground....no track. no GPS warning, but I wasn't monitoring it during the flight, just using it to record.

A couple of times I have seen tracks on landing then when I upload to the cloud nothing appears.
