Permission Request for Apps

Hi,

I got a Probleme with one App in the App Store for SharePoint.
I developed an App which Needs Access to the Term Store. I developed the app wich permission request for read on site collection. In my testing Office 365 developer Environment everything works fine, but in an private Office 365 Environment I got an "Access Denied" when I trying to Access the Groups of the Term Store.

So first my question is how can I test my App for such a Scenario in my Office 365 Dev Environement?

And hoq can I test the others planes for Office 365?

Thanks for any advice.

With kind regards, Anton Flichtbeil "SharePoint App Developer"
