This may be an O365 issue, however I am unable to manually terminate a workflow in Nintex Workflow O365 as of today. When I select the option, it simply runs. It has no effect if you try to kill it in Workflow Health. I've tried using a different approach to get rid of it, but it won't go away. This has been the case all day and across all of my site collections. All week long, it performs admirably.

Is anyone else receiving this or has anyone else seen it before?

Is it a Nintex or an O365 issue?
