I have a verified FB (17k), verified Twitter (21k), and my verified FB and Twitter accounts are linked to my UNverified Instagram account (6k). I am active on all, with several posts per day, every day. I have a personal website that has a domain which includes my name, and links to my social media accounts. My first post on Instagram was Jan 2011 and I have almost 2k posts with plenty of engagement from 100-1,000 likes per post, comments, etc. I've done everything right, but for years it remains unverified.
What am I missing?
