Hi again, @mortada03 !
Thank you for following up with that additional information.
Now that we have ruled out of the potential of an application causing this pop up, are you able to confirm what the name of your theme is? This way I can look into the features to determine if this functionality is built into the theme. This will also help determine if the popup is being caused by a piece of code that may have been added manually, or left over from a previously uninstalled application.
I look forward to hearing from you so that we can continue troubleshooting!
