Query: This Popover Pan Stucks

It worked for a few times at first. And now it's virtually impossible to remove stuck popovers from this pan. It's the gracious replacement pan from Williams Sonoma after the first pan hopelessly clung to each popover too. The instructions were followed to the letter with the same stuck results. It appears the "non-stick" finish might disappear with use. Vegetable spray and chunks of butter as directed didn't resolve the issue. Perhaps there is a pick and shovel popover removal tool that should be included. Will return it.
