Sorry if this has been answered previously I couldn't find anything regarding it. We have over 100 site collections that use Nintex Forms and Workflow in Office 365. On a number of the sites it is showing that the app requires an upgrade. Is there anyway to easily (via Powershell etc, I've seen this: How to upgrade SharePoint app where the SharePoint app is installed on 20+ sites? - SharePoint Stack Exchange and these: Get-SPOAppInfo) but there appears to be no upgrade as per onprem. I don't want to have to go and manually upgrade all the sites.
Thanks in advance.
