SharePoint Add-Ins will stop working for new tenants as of November 1st, 2024 and they will stop working for existing tenants and will be fully retired as of April 2nd, 2026.
Will the K2 App for SharePoint App be affected by this change from Microsoft?
Yes it will. We have already released a SharePoint SPFx App for 5.7 for any new integrations/installations. We are currently working on a migration tool to move any Add-In based integration to the SPFx app, provided you are on a supported version. See the news post for the details:
