Hi,
I created app using developer site and then published the app.
Took the package to app catalog of office365 and added it. The app is working perfectly.
Now I added the app from site content to my publishing site and it is working when I am clicking it.
The problem is when I am trying to edit any page and insert that app from ribbon using Insert 'App Part' , the added app in site content is not shown over there.
When I go to site content it is present but unable to add that app on my page becauz it is not available on ribbon.
Please help on this. I am using trial Office 365 site for development purpose as of now.
