Sophos MDM IOS 9.3.2 // VPP for free apps required again!

Hello Folks,

since the new IOS 9.3.2 I have to link the VPP license to the device(s) again, even when the app is for free. I double checked it. I've checked the following:

## Iam using a brand new AppleID with almost no app linked to it! ##

1. IPad Air2 with IOS 9.3.2 - Can't install the Cisco Any Connect app via MDM Error: ( The iTunes Store ID of the application could not be validated )

--> this app is for free in the appstore!

1.2 I've linked the App - VPP to the device, try to reinstall and the task appears on the iPad ( do you wish to install .... ) - I abort it.

2. IPad Pro with IOS 9.3 - Same app, No VPP link, Installation worked via MDM without the Error!  - I abort it.

3. IPad Pro with IOS 9.3.1 - Same app, No VPP link, Installation worked via MDM without the Error!  - I abort it.

So I'am not able to install free apps on my devices, without clicking every single app and link the VPP to the Device. This costs time and I'am not willing to do it again :D this was a pain in the ass while the IOS 8.XX Versions. 

I've called the Sophos support and told him my "story" he will forward it to their Backend-Support.

Do you guys got anything so far?
