I had this situation in Aug 2023. After waiting for a month after approval, I created a service request for missing document. After waiting another month, I ask my senator for help. I received the document within 2 weeks

@Bob Zeiger That sounds rough. Mine been only a week. So, hoping it gets produced soon.

mine approved April 3 and was produced April 4

@shob demax My wife had a similar timeline with document being produced the day after approval.
