@Bret_Iron I am so sorry for all the confusion!
You see, the threads you’ve commented are dedicated to the Google Reviews app only:
As my colleagues from the Support Team correctly mentioned, this feature unfortunately isn’t available for the All-in-One Reviews app. However, this idea is already on the Wishlist - Reduce Cache time.
Please upvote this idea if you’d like to have a reduced cache time in your All-in-One Reviews widget
