Storefront Link Missing

I noticed today that the Storefront Link from the Sold By page is missing on my items.

It was there last week. I make my own items and my brand is listed as Generic.

I am a Personal account using FBA and have items in stock.

Are there prerequisites for a storefront that I do not meet? If so, I'm wondering why I had a storefront for almost a month and now it is no longer there.

I am on with support chat now but they seem to be having a difficult time with this issue and I've been transferred a couple of times.

Thank you for any insight.
