I have been testing out a JavaScript Custom Action add-in injected a test script into my SharePoint Online master page. During one of the change and deploy cycles this seems to have gone awry as a previous version of my Script Action has gone rogue (One!). I can't remove this older Script Action which means the script.js fires always, regardless of if I add or remove the current version of the Add-in
• [ScriptLink] {41d1c22d-9b4e-4eb9-aaa4-ed66683e938b} ScriptSrc=null Sequence=0
Any ideas how to nuke this instance please?
