Has anyone else run into this? It seems to be specific to my Moto X and does not occur on my Nexus 5 or Nexus 7. If I have an app updating/installing and turn the screen off, no further action occurs until I turn the screen back on. I actually first noticed this immediately after a factory reset. When trying to update the ~28 apps that were out of date I selected Update and then turned my screen off... After about an hour I turned it back on, and none of the apps had updated. They started updating as soon as I turned the screen on.
I have tested this on WiFi and mobile data, and I do have background data enabled and WiFi set to always stay on.
