I don’t mean to a wise ass, but there’s got to be more to it than that. I follow them both, and I’ve never gotten anything from either of them, not an email, no notifications, nothing. I will freely admit that IG is the single most confusing site I’ve ever been on. I don’t get how it’s supposed to work, and that maybe the entire damn problem. 
I’m with @Tappy, all see are pictures that I have to click to even see a description.
Is IG the only way to be a tester?
