How to see App Store reviews for “All Versions” of an app on iPhone iOS 12

[garysch37]

Is there a distinction between reviews for the “current version” and “all versions” in the App Store app on the iPhone? I seem to remember being able to switch between the two on my iPad 3 and/or desktop, but I don’t see that toggle option on my new iPhone X running iOS 12. I find it handy to be able to read reviews of older versions of an app because they are so numerous compared to reviews for the current version, and so that gives me significant additional information about an app before I purchase it. Thank you, Gary
