Sometimes when you are installing LiveTiles design, you may come across the following error:

Your tenant administrator has to approve this app.

Even if you are a tenant administrator, on occasion this message will appear. To fix this error, you will need to request approval for the app. Once you have requested it, you will need to go to the SharePoint admin portal, which you can find in the top right corner under admin on office 365 and then under admin centres.

The App Catalogue area

Once you are here, you will need to go the apps and the manage apps section. Once there, you will then be able to go to the apps for approval. Once in this section, you will need to click on the name of the app. In this section, you will have a button which says approve, which will allow the app to be added to the product.
