frozen video

I am completely confused here. After doing a sensor calibration (due to an error I was getting that Precision Landing required a sensor calibration) ... I took the Mavic Pro up today and started seeing some pixelation ... then the video froze ... then absolutely no video at all!!! I've since...

Coldpack strapped to smartphone stops overheating (which causes video corruption) with the Mavic Pro after recent upgrades. Not really a practical solution but works very well;.
