When you click on a category other than the category that is open, the page refreshes the old category products coming, then comes the new category. Are these settings related? I hope I can tell. I added a video
Our AJAX requests have a timeout of 5 seconds and if they don’t get a response from the server at this time the page will be loaded in a natural way. If you need, we can give you an instruction how to increase this time to 10 or 15 seconds but it is not a solution and you can try to disable this function completely.
