Facebook Instant Articles on WP MultiSite

It seems that facebook's claim url process is not recognising the meta property that I inserted into the head of the root site. I can see the meta in the source code, but Facebook returns a
"Something went wrong. We're working on getting this fixed as soon as we can. You may be able to try again." and then once hitting the claim button again results in
"The fb:pages tag on the url doesn't contain this page's id. The url has fb:pages tag but they don't have this page's id. Please work with your developers / webmaster to add this tag to your website."
Anyone having this issue or has a fix and has Facebook's Instant Articles working on a Multisite?
