Not sure if some of these have been addressed in the latest firmware update:
1) lap time and TSS continue while unit is paused
2) if HR strap gets out of range from head unit, it does not reconnect when back in range during a ride (think coffee shop stop!)
3) longer workout files seem to have bugs - for instance 3x10’ of 15 on 15 off intervals setup in a fit file will work fine for first two sets, but last set the power targets will freeze, graph will advance to the end of the block, but timer will continue as set in fit file.
Aside from these few minor issues, I definitely dig the Dash! That new lap history chart is going to be key!
