Protect Plus Discount not applied on Amazon

Ring Protect Plus account and Prime account linked. One the app I select the items I want and it sends me to Amazon. No discount is added at check out. I got to ring.com and I can get the discount through them. The help section says the discount is only through ring.com however, it also says the discount is available if the accounts are linked. Which one is it? Can I do it or not?

Right. 10% only applies to direct purchase through Ring. But wait until the next Amazon Prime Day and save way more than 10% on Ring products plus excellent customer support like tracking, returns, etc.
