Creating brand store in Amazon after USPTO

We filled for brand registration in USPTO. It can take up to seven months but Amazon allows to create brand store with application number. Store was created but strangely it can be accessed only with direct link. Pressing brand name on the product page or visit store from seller description page doesn’t open store. Also direct link is kinda strange, couple of years ago you could type www.amazon.com/brandname and it led to the brand’s store but now its long url address. Did i mess up smth or Amazon has changed its procedures?
