GDv2 Upgrade Problem – How to use Contact Form 7 instead of Ninja Forms

How to use Contact Form 7 instead of Ninja Forms that users are able to contact listing owners directly.

Dear support team,

I try to upgrade now from GDv1 to GDv2 with my dev2 site by using your instructions > https://wpgeodirectory.com/docs-v2/geodirectory/upgrade-from-gdv1/

There in the video at 17:45 you explain to use Ninjaforms with preset integrations from geodirectory.

As I tried to use these Geodirectory forms they are not displayed in my gd sidebar.

Listing Example > https://dev2.worldcheckin.com/gastronomies/united-states/california/los-angeles/restaurants/yup-dduk-la-1/

I guess this is related because I am not a ninja form license user and need to purchase one.

But instead of causing costs, why we are not able to use contact form 7 and if, how to enable the contract form via CF7 that the user is able to interact directly with the listing owner as it was setup in GDv1?

Can you please help me to proceed with a contact form 7 instruction or template?

Best Alex
