Is anyone else having difficulty using Webflow pages as content for Facebook Page tabs? I can “embed” pages from WordPress, Squarespace, and other hosting platforms in custom Facebook page tabs with no problem, just not pages hosted on Webflow sites.
There is nothing special about the pages I’m including in the tab, no page from any of my Webflow hosted sites work.
In the tab on the Facebook page, I get the error message:
Error 503 backend read error
backend read error
