Small custom Elementor tasks and questions

https://lemontreefilms.com/ I have a client who has hired me to design a pretty custom and involved site. I have taken it as far as I can, but need help with these items: • Some mobile experiences are reporting issues loading GIF videos and some are reporting errors • Overall Site performance help • Screen scaling issues with the "BOOK NOW" button + Social icons in the top right of the site not staying centered in the container We might have more items pop up, but those are the main ones for now. I'd love someone who is more knowledgeable on the back in to help. Thanks!
