I'm not sure to understand what happens when you confirm the updating operation. Does it somewhat freeze (I mean, not app rebooting with the new version is happening)? Maybe a new OS restriction?
Your last sentence: does it refer to manually launching the app from the Home screen? If yes, how can it be both updated and showing the old version number?
No, it doesnt freeze.
I click INSTALL, it installs
I click (after that) OPEN to start.
But it didnt.
WHen i look at the "taskmanager" i see the App (without startsecreen) in the back.
When i click THAT one, ist starts
I made an Testapp with an extra button on it that will be downloaded.
I am running local a version without that button - after updaten (as described here) the button is there but: shows old version
