Changed:

• The criteria for ‘no pedalling detected’ to improve the intermittent zero power readings

Fixed:

• Stopped the power from intermittently dropping to zero on some AtomX & Nucleus bikes
• An issue where the revolution data continued changing on screen despite the ride session being paused
