Thank you for using our product, Regarding this Autoplay not working issue. we have used a testimonial module for this section this module is no more active now. Instead of this Testimonial module, we can use the SP Page builder Testimonial Carousel Addon You have a Full Control when you use this Addon instead of the Testimonial module
Note: We already started to working on FactoryPress theme update work. during this update, we are going to remove this module and use Testimonial Carousel addon for testimonials sections to avoid this issue.
Why we don't use this addon during the Initial release of the template means during that time SP Page builder doesn't have this Testimonials Slider Addon It was added recently. so we are going to replace this in a future update.
If you feel not easy to configure this addon in your site kindly share your site login details along with the FTP or Cpanel login details with us we will help you to replace it.
Please do take some time to read through some of these links:
