Flow fails with error "integration disabled in showtime"

Flow fails with error "integration disabled in showtime"

I have built a flow to automatically add registration to a Showtime Remote Session. The flow is triggered when a Zoho Form is submitted and the details submitted are used to register the person to the session. While the Test & Debug shows that the flow works, the live flow always fails with the error message "integration disabled in showtime." Appreciate assistance in getting this integration working.
