I have many site collections that use a SharePoint Add-in common for most of the pages in sites and subsites.
Each time when I create a new version of add-in and upload in appcatalog, I have to manually go to all the sites and follow steps - s
ite contents> select add-in > click on upgrade > Get it .
Is there anyway such that if I upload new version of an app it should automatically upgraded in all the sites?
Also if new app id added to appcatalog, can it be added to all sites , even trust it should also be taken care for itself.
I have tried below link from which I was able to only deploy the Add-in but not install it.
