Question about Sharepoint App Permissions

Question

I hope you guys could help me out. I have an average understanding in Sharepoint as well as Administering it. Currently we have Sharepoint Online Plan 1. Now I will describe my situation below.

A user has a site collection and I created a Sharepoint group for that user. Pretty much she has the power to do anything inside her site. Also I made myself Site Collection Admin for the site and not her since I want to have some sense of security. Anyways, she requested to enable the ability to add App from Sharepoint Store. And so I set up my first App Catalog and also configured the App Purchases and Apps for Office from the Store to "Yes". After I deployed it she can now add apps with no issues.

However, there is only one app that is showing "Sorry, only site collection administrators can add or give access to this app." ?? Which confuses me... are there some apps that won't let the user add an app or restricts the user from downloading/installing apps even though I have given them full permission to do so? Is this a permission issue? I know I could add it myself since I'm Site Collection Admin. I'm pretty much stumped as I search the net.. Hope one of you guys could help or explain why is that so? Thanks so much! -Matt

Answer 1

Since I'm the Site Collection Admin, I decided to add the app for the user.

Answer 2

This is because the app requires tenant level permissions. I don't know when or why this change was made. This requires you to install the app for your users (or approve the installation, if they submit a request). This article shows how developers can work around this while debugging.
