Key vault create new version of an existing Certificate

Question

I try to create a new Version of an existing Certificate inside an KeyVault.
I had already the notification that it is done, but I still see the old Certificate as top of the List.

I tried again and now I get the following error Message:
A new key vault certificate can not be created or imported while a pending key vault certificate's status is inProgress.

The first try to create a new Certificate is now more than 20 minitues ago. As I said, I had already the Notification that the new Certificate shout be finished created now.

What can I do now, can I cancel the old request?
