No option to “show all reviews” in App Store

I can view the “most helpful” reviews, but I see no option to “show all reviews.” I’m pretty sure that option was there in earlier versions of iOS, I think to the right of the reviews (it could have been below the reviews but I don’t remember for sure), but was it removed with the iPadOS 18 update which my iPad got today? Why would it be removed?

Also, why is there no options to sort reviews by “most critical,” “most positive,” and “most recent” as there are in the iTunes Store?
