Powermatch stopped working during interval



Today I was doing a 2x20min workout with my Kickr Snap (which was being controlled by my Stages PM through Powermatch). During interval #1 everything seemed ok, and the power reading on my head unit (reading the Stages PM) seemed to track quite closely to the actual power I needed to follow for the interval. However, on the 2nd one, it seemed to stop working. I was supposed to hold 235W for 20 minutes however my head unit was reading low 200`s.


Anyone had a similar problem? Maybe my Power Meter lost connection with the trainer?
