Hello friends, thanks for your comments here!
We understand your wish to have new reviews displayed more quickly in your widgets, and we’re truly sorry that there’s no option to control the cache time at the moment.
However, we’re working on adjusting cache times based on the plan you choose, and this will be our first step in that direction. We’ll be posting updates about this change in this thread: Update Displayed Reviews Every 24 hours (Reduce Cache), so you’re welcome to follow it.
