For the 70 mb download on the 26th, that was the firmware upgrade to 1.7.0. I am still on 1.7.0. But I don't understand the almost 900mb of uploading. That shouldn't be needed for a firmware upgrade. Just curious since we have metered internet from Comcast and don't yet get too close to the limit of 1000GB per month but if our trend continues (as more 4k shows appear on Netflix) then it may become a factor. Just curious if any of the other owners saw similar data usage or not.
