I am doing integration with C4C and Facebook in testing tenant. All settings are fine and ready to go live. As the social channels cannot be move to production tenant directly, I create another social media channel in the prod tenant with the same FB App ID. I changed the URL in Facebook APP from C4C test system ID to Prod system ID.
However, here is the issue. After I changed all the site, I try to "Connect with Channel" when creating a social media channel. It does not connect successfully, and shows a blank page, as shown below.
Could any expects please advise how to move the FB social media to production? We do not expect to create one more FB App ID to do so. Really appreciate if someone can help. Thanks in advance.
