Following the MSDN article here: http://office.microsoft.com/en-us/sharepoint-help/use-the-app-catalog-to-make-custom-business-apps-available-for-your-sharepoint-online-environment-HA102772362.aspx?CTT=5&origin=HA102772716 to add a custom sharepoint app to the App Catalog on a trial admin account of Office 365. The app catalog was automatically set-up (or at least I didn't create it).
Step 2.2 in the article directs me to "In the relevant apps library, click new app". I don't see any option to add a new app. It could be that I'm not seeing it or missing a step.
What/where do I need to do/go to add a new app by following step 2 from the article?
Here is a screenshot of what I'm seeing. The upload document is greyed out along with other options that I would have expected to be available.
