Windows Phone Store going mad - users annoyed because update false alarm

It seems hand in hand with the improvements Microsoft claims to have been making to Marketplace,  there has also been increasing chaos on the consumer end.
The latest upgrades are provided Adobe Reader version 10.1.1, which in fact fell back application version 9.0.0.

Our comment about this issue, there maybe Microsoft are editing something on their Windows Phone Store, making the system update message confused, from upgrade to downgrade. Microsoft probably already know the problems and trying to fix this problem, maybe 10.1.1 will soon be back on our Marketplace for update (again). So, if you are using the new version of Adobe Reader, do NOT update!

Update: The issue may be limited to the US Marketplace
