OK, so on my last failed attempt at any reasonable distance (flat front tyre), I note that the Findmespot tracks recorded my whole journey correctly. But once again, Spotwalla did not start recording until I was half way through the ride (started around 07:30 and it kicked in around 11:33). That's about 4hrs from the actual start.
So, now I'm wondering ....... if I set my Spotwalla trip to start at (say) 05:00, is that AEDT or some other time zone? On this particular trip, I set the trip in SpotWalla to start at 05:00 in case I did get a burst of advanced energy. But no recording until 11:33. Is there a time zone difference setting here I'm missing ?
