I have a flow which a user can trigger in a SharePoint list (for a selected item). It worked for months but suddenly I get "Status: 403. Access denied. You do not have permission to perform this action or access this resource."
I am SharePoint admin and I am owner of the flow. A co-owner doesn't get the error. I recreated the flow from scratch and deleted my SharePoint connection from connections, but I still receive the same error. I even created the same flow for a different list and I get the same error again. I get the error for the action "Get Item" from SharePoint. It is for SharePoint Online.
