Amazon Onsite Help

Okay I’m having a hard time telling if my videos are eligible for onsite commissions?? I am apart of the Amazon influencer program and have uploaded 3 videos to my storefront. I see people talk about a “blue lock” on their amazon associates central site but is that a thing of the past because I don’t see it? How do I know if my videos have been approved/chosen for onsite commissions??

Also has anyone who started doing this recently made any decent money at it? Or is it just too over saturated now??
