Issue. App needs background data

My phone had a battery saving app loaded and was restricting background data as well as blanking the screen. You'll notice a couple if diagonals on my route where the screen was off and GPS jumps from last know position to current position. I caught it with the first one and then watched for the rest if the ride to see if that was the case. I'll have to watch for that setting in the future or see if I can exclude ESR.
