1. I have a Facebook account and page for the business I want to use this plugin. I don’t have a personal Facebook account, but nevermind.
2. I granted all the permissions like I mentioned in the initial post
3. I understand that something is wrong, but I did complete the integration with the account and with the page. This is what I’m reporting.
4. Again, there is a Facebook business page connected, which was integrated earlier. I need this plugin to work for an existing business page; in the first step I tried to use it with a test account, but in the second step I integrated the real business page and I got this. I did this a couple of times by removing the integration from facebook as described in the documentation, but I got the same result.
