I am trying to follow the add-in update process described in Update SharePoint Add-ins but on a developer site.
Where I got stuck is the point in the document that reads
Then upload the latest version of the add-in to your test site's add-in catalog and update every instance of the add-in.
As far as I can tell, the "Apps in Testing" document library is the add-in catalog on the developer site. However while I can upload a new version of the add-in package there, there seems to be no way of updating an already deployed instance of the add-in.
Namely, I just cannot complete this part of the instructions:
- After the latest update is uploaded to the add-in catalog, open the Site Contents page on the website where the add-in is installed and choose the ... button on the add-in's tile.
- On the callout that opens, choose the About tab. On the About page that opens, there is a notice that a new version is available.
As there simply is no About tab on the callout that's supposed to open in step #2 - only Details, Permissions, and Remove. Could it be because the add-in was initially deployed from Visual Studio and not by using the developer site's "New App to Deploy" function?
