Major Incident Management Playbook - Resolve Activity Issue

[Ash33]

Hi all

I am unable to Resolve the Major Incident in the playbook activity. After clicking the Resolve button, nothing happens. I tried following these KBs as well, but the issue still persists. https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB3048503

Can someone please advise?

Regards,

Hi @Ash33 ,

Was this working previously? can you check this in sub prod instances

It works in sub production, upon investigation I can see this Activity UI Layout is missing. I can't find how is this created? The version related list is empty and xml shows Created By Admin.
