It would be great to see an in-progress popup for any critical operation (i.e. snapshot/publish etc). Currently, the blue buttons are difficult to see if they've been clicked and further clicks are allowed.
Given that you may be publishing this feels like a fairly major UI issue.
Thank you for your feedback. We're aware of this issue and a fix is being developed for an upcoming sprint, the fix will prevent multiple clicks, and you will see an indication that you've submitted the form.
