Login not shared with using free version plugin

Hi there!

I just installed your free version to test the correct functioning of the plugin and the connection of site A to site B do not work!

Here is my configuration (latest version of WP):

– my site A is https://odenth.com/
Your free plugin is installed with following settings (see screenshot A1 & A2: https://odenth.com/RezOdenth/IMG_diabolik/A1.jpg + https://odenth.com/RezOdenth/IMG_diabolik/A2.jpg)
I’m using in this case a memberhip plugin called “PrivateContent” which syncs members with WP users (see https://codecanyon.net/item/privatecontent-multilevel-content-plugin/1467885)

– my site B (buddypress based) is https://odenth.com/RezOdenth/
Your free plugin is installed there with following settings (see screenshot B1 & B2: https://odenth.com/RezOdenth/IMG_diabolik/B1.jpg + https://odenth.com/RezOdenth/IMG_diabolik/B2.jpg)
Obviously the two sites HAVE SAME TOKENS AND KEYS (same security settings)

1/ Why does the connection not work with your free version?
2/ Do I have to buy the pro version to create the login in site B and therefore be able to connect/log in site B?
3/ Could it be my memberhip plugin called “PrivateContent” which raises the problem (even if ot is synced with WP users)?
4/ What happens if the pro version does not work? do you refund this purchase if that happens?
Thank you for your quick answer as I will be happy to purchase this plugin to fix my problem.

best regards
