Same extact problem here for over 2 months, not all recordings or channels, very irratic. More then 1/2 of my streamed recording are incomplete. And just in the last week not all DVR recordings are showing up for streaming app. Windows, Android, and IOS all missing the same recordings that show up on the DVR and conneted boxes??? Outsiders from 3-14-17 WGN America, and Quatico last night 3-20-17 ABC.
This technology S/B getting better, not deteriorating!!!
I've had the same problems ever since they changes to Xfinity Stream. Half my recordings are either incomplete or missing from my cloud DVR. It is very frusterating because I travel alot and used to take shows with me to watch. Now it's useless.
