Bug report - 'Snail trail' usually fails to display on igc replay mode
The snail trail fails to display in the 'Thermal Assistant' widget when replaying an igc. It is often present if the igc is replayed from the start, but if you skip to the middle of an igc then it will disappear. The 'XC Assistant' widget which is on the same page displays the snail trail well.
The settings on the 'Thermal Assistant' widget are:
Heading at top
Map scale - anything
Display map scale - off
Display airspaces - on
Tracklog length - 2 min
Wind computation - Classic
Show navigation - do not use
Show latest - 2 thermals
Show wind - on
Show sun - off
Thickness of lines - x 2.5
