Load Balancer used to work fine with old certificate - which now needs to be renewed.
Since there is no option to edit existing certificate, I have added new one
Old certificate still exists since if I try to delete, i see following - which is fine.

My problem is that when I try to associate / attach the new certificate to listener & backendSet, it is not listed. Only the old certificate is available.
I have waited a while and cannot find option to reboot LB - am I / documentation missing a step ?
Believe I am using the new Cloud interface - but assume that cannot be root cause :)
Apologies if this is in wrong Forum.
