I was having the same issue and learned that more back foot is at least part of the solution. More back foot helps get the Vega up on an edge.

RE: Plus disengages suddenly/footpad sensor error
@mtruby82 I get the same thing sometimes, usually carving tight turns at lower speeds. I think it might be from my heel/toe getting light on a pad during the turn...frontside turn lifts heel off the pad a little, backside turn lifts toes.
I haven't noticed any effect at all except the app notification. ¯_(ツ)_/¯
