One Android enterprise device in our Hexnode setup would not update a managed app. Updating from Google Play failed even when trying both the work account and a personal Google account. I also tried pushing the update from the Hexnode portal using the install application action, but it did not complete. Restarting the device did not help, and the Scan Device action stayed in Pending. Other devices were updating normally, so it looked isolated to this one device. What should be checked in this case?
