App Parts and Custom Actions in SharePoint apps at tenant scope

Question

I have installed a sharepoint app at tenant scope. Source 1, Source 2.

In my app I have an app part, which is available in App Catalog (where the original app is installed). However on all other sites, the app part is not available, even though the app is there as a FullPage (immersive) app in Site Contents.

My question is why it is so, and my second question is:

Could it be possible to provision app parts to all sites from an app installed at tenant scope?

Answer 1

Not possible. Source

Limitations of tenant-scoped apps

The following kinds of apps cannot be batch-installed:

• Apps that contain a custom action for the ribbon. (Custom actions that are deployed as menu items are allowed.)
• Apps that contain an app part.
