SEO tab is missing under Marketing

Hi experts,

My client recently gave me a collaborator login to edit their Website. I need to set their title tag, meta etc. I see from online instructions that there should be a tab under marketing for seo, but it's missing. The only options I see are email marketing and instagram.

Thanks for the help! 

I'm not seeing a problem here for v7.0 and v7.1.

This is version 7.1. Screenshot attached 

This is what I'm seeing.

ok. any ideas?
