Up until now, you could only see your own review edit history on the Google Play Store, but this is changing as of today. Google is now making everyone's review edit history publicly visible, although the feature is currently live only in the Play Store app, with the desktop version expected to follow suit in the coming days.
If you want to view the edit history of a certain review, just tap the overflow icon to the right of a text, where the rating and flagging options are, and you'll see a new "View edit history" button. Tap that and you'll see what changes the author has made to their review.
This is very helpful if you want to see how users react to changes introduced in new updates, although it can also be a bit annoying at times, considering that a large chunk of the edits submitted are fixed typos.
Fortunately, if you want to remove a review that you have submitted to the Google Play Store, you can do so by permanently deleting it.
