I have created a couple of test surveys in Forms pro (in a production environment)

I have distributed them via email (and i know they arrived and were responded to because i was the one that responded)

When I look at the surveys on the Forms Pro home page, I see each one has some responses (1 says "2 responses" the other says "6 responses")

However, when I open the surveys and click on the responses tab

it just shows me the number of invitations sent and responses is "0"

 

What could be the problem here?
