Failed to measure with BPM+ after upgrade to 5.2

I'm getting the same issue

It seems the new app version will not keep the phone "awake", therefore once the phone goes to sleep mode the measurement ends. My temporary solution is to set the sleep mode from 30 seconds to 1 minute such that the measurement can complete. Still, hope the problem will be fixed soon. Hope it helps. 

Thanks! That worked for me too.
