@Nikita_Kurguzov - to refresh my (and the Community’s) memory, this “delete” is accomplished via the Classic Experience in MS365 Apps here: “https://your-tenant-here.sharepoint.com/sites/appcat/_layouts/15/tenantAppCatalog.aspx/manageApps?source=classicAppCatalog”
Side note: Related to the mandate in this banner: “Starting April 2, 2026, SharePoint add-ins will be retired for SharePoint in Microsoft 365 and users will no longer be able to use SharePoint add-ins. Installing SharePoint add-ins from the SharePoint Store will not be possible as of July 1, 2024.” Microsoft announcement about add-ins - #5 by shedev
When I visit this location and click “Get it now”, it terminates with this screen suggesting I have version 1.1.0.5 already Added with a note “Good news — all sites in your organization can use this app now” but as shown above, it is 1.1.0.1. If I delete the Plumsail Forms above (1.1.0.1), will it automatically update with 1.1.0.5? I have this documented but now not sure of my notes.
