Hi there,
Kindly open up new threads for additional questions as it will help us to focus on each issue and give you a better support which you deserve. Having a long threads makes the maintaining job harder and also it will be harder for the other customers to find the correct information if they have similar issues. You are always welcomed to reply to this thread to follow up the same question.
The Ethos Post Carousel feature does not have the Autoplay functionality. This will need custom development and it is outside of our support scope, but if you need that we can give you instructions on how to do so but we will not be able to implement the functionality.
Kindly open up the new thread for the request.
Thank you.
