Use the SEO stacks built into Foundation, the RW8 stuff is limited.
Setting up the Twitter and FB stuff is a lot easier.
If you go this route be sure to disable the social stuff in RW8
I don’t have or use Facebook but they have a OG tester here https://developers.facebook.com/tools/debug/
I’d test it there and not in a 3rd party app. Twitter have a similar tester.
You should use consistent URLs throughout. In one part you have the URL with WWW, and in the other without WWW. It makes a difference as technically they could be two different websites.
What do you suggest to fix this?
I just changed theURL on the FB Open Graph as well as the Structured Meta Data to WWW.
Also, in the general settings the web address is WWW.
To my knowledge, Instagram doesn’t have a separate set of meta tags.
I haven’t found anything or tested out Instagram, but my assumption would be since they are owned by Facebook they’re probably using the Facebook Open Graph standard meta tags.
