Thanks for getting in touch and reporting this bug! We have just pushed out a fix; can you confirm that the “Thumbnails per page (mobile)” setting is working as expected now?
As for autoplay on mobile, unfortunately this feature is not available on iOS and Android devices. This is a limitation of the mobile operating systems, which generally prevent apps and web pages from downloading and starting media when it is not explicitly requested by the user (e.g. via tapping on the play button on the screen). Sorry we don’t have better news for you in this regard!
Please let us know if there is anything else we can do to assist, and thanks for using TubePress!
