Cannot complete all intervals during workout

Hi,

during a workout the app suddenly stops controlling the kickr and I'm not able to complete the interval training.
This seems to happen randomly and when the issue occurs, only the timer works, all the reaming intervals simply disappear from the schedule

When it happens, I can only complete the intervals by controlling the kickr manually with the Kickr native apps

How can work around this ? I have the latest version and I'm on a mini iPad with iOS 8.2

Thanks

Regards
Vincenzo
