Android tablet not auto-updating applications I have an android tablet that is leveraging an internal company network. It appears that this device and all others similar to it are not auto-updating applications from the Play Store even though all the appropriate settings are correct.

I can see there are apps to update and I can even manually update an app but the auto-update never runs for any apps.

The same tablet in my home network will run the auto-update.

Could the companies internal network somehow be blocking the auto-update? If so how does the auto-update work so I can add exceptions to the firewall.

UPDATE

This device is a HP Slate 21 Pro All-In One and has both a WiFi and an Ethernet (wired) connection. We found that when the device is connected on the company network using a WiFi connection it DOES auto-update but it DOES NOT when connected using the ethernet connection.

My guess is that the Playstore (GMS) is checking if there is a WiFi connection and if so downloading the updates and if not a WiFi connection it does not download the updates. Similar to how a true mobile device behaves where there is either a wifi or cellular network connection.
This issue has been reported to HP and has been confirmed it is an issue on their end or with the Play Store software.
