The checkout page loads after a while, but the express checkout part of the page does not load at all, how can i fix this?
I did a quick test here on my laptop and those accelerated checkout buttons did show. Are you still seeing the problem? If so, consider testing on a different device just to give you some confidence that it might not be an issue that everyone sees. The checkout itself also loaded quickly for me.
If you can consistently replicate the problem I would suggest contact the Shopify support team - and be ready to share things like browser, device info, etc.
