Is the item preview edit button missing for anyone else?

I’m keep losing the edit button from the right bottom of item page. Mine disappeared as I was using it on Monday. For me, it’s a great tool to see exactly what my customer sees. And I find it easier to see typos or other errors. I’ve lost it several times before but it always reappeared after I reported it. But now support tells me it’s not longer available. Does anyone still have this?

Hi,

Can you share your store url
