Stan, Who did you order it from? I had the same problem. Everywhere I looked it was on backorder including Nikon. So, I just decided to order it directly from Nikon and wait it out. This was at the end of September. In less than 2 weeks they shipped it. Received it on October 10.I'm still waiting (Belgium) on the TC 1.4 III, on order since June 2021.
Is this a world wide issue?
