Office 365 changes al the time, I tried to see if I could Disable the Video Portal, to test what happens if you delete de Video Portals.
En my Tenant Admin for SharePoint settings I disabled the Video Portal:
I saw my Video app disappear from the App Launcher. Now it is time to delete the site collections.
So at this point I am a Tenant Admin, and I want to clean my Site Collections. The Video Portal creates a few SharePoint Site Collections and one of them is named Hub. This is the main Site Collection for the Video Portal where all your videos are shown.
So I Delete the Video Portal Hub Site Collection. and delete it from the Recycle bin.
Now it is time to recreate this Site Collection? I turned the Video Portal back on using the setting above. I hoped that it would recreate the Hub but that didnt help. Only the Video App in the launcher came back with a nice 404 Page Not Found
The Solution for this issue is to go to the url Bellow
This will recreate the hub Site Collection.
