"This feature is not supported" when you activate the Announcement Tiles feature in a site
Consider the following scenario:
You browse to the Site Settings page in Microsoft SharePoint Online.
You click Manage site features.
In the Announcement Tiles feature, you click Activate.
In this scenario, you receive the following error message:
This feature is not supported in the current site collection's version.
This error occurs because the Announcement Tiles feature is available only on the My Site host on which the My Sites websites reside.
