Go to Review Pops > Triggers > Condition to show, and you will see many display options here, including:
If you do not want review pops including some bad words, please consider to use option "Hide reviews with keywords" wisely
In order to avoid review pops appearing continuously after a fixed period of time, we have added Random option here (for 2 variables, First Popup Shows After and Delay Time Between TWO Popups), where you can configure waiting time between 1 second and 100 seconds.
There is a limitation for monthly popup views, 20,000 on ESSENTIAL plan, and 100,000 on PREMIUM plan, so you can consider to use Display Limits feature properly.
In case you are in PREMIUM plan, and you already reached 100,000 limitation before ending of the month, please contact our support team for a solution then.
Should you need further support, please feel free to contact us via live chat or email us at email@example.com
