I am having the same issue with the Netflix app right now. It says
'Pending - Application is not available to install'. JAMF said to talk
to Apple. Apple said to talk to Netflix. Nothing from anyone. This app
used to work as I can see where it pushed...
We have seen that with ipads in single app mode. When a new version of
the app that is in single app mode comes down to the ipad, the app
closes and the three or four apps we left on the device show as
'Cleaning...' and you cannot access any of them....
