MacBook Air running Sierra 10.12.1, iTunes 12.5.3.17
Open Apps/ Updates
I try to update an individual App and it fails immediately with "Unknown error 8392"
I attempt a couple more times and it updates!
This was the case on the previous level of iTunes as well.
MacBook Air (11-inch Late 2010), macOS Sierra (10.12.1)

I have 150Mbps up/down here in NY and 200Mbps in FL but the same problem happens with regularity even with no other apps running or anything else using the network but the MacBook Pro Retina mid 2015. Then eventually the downloads complete. The user experience decline frustration has gotten steadily more visible over the last few years.
