iTunes connect third party quesiton.

When submitting there's a new question, alongside with the one for the encryption:

"Does your app contain, display or access third-party content?"

I guess showing ads means I should check "Yes", but I checked "No".

Should showing ads be checked as "Yes" and how to correct the answer?

I rejected the binary in order to get trough the process again, but now it shows only the question about the encryption.
