Hi there!
I tried to replicate the issue on your site using a mobile device, and I can confirm that this doesn’t appear to be a page speed issue. It seems like the page HTML, JavaScript, or CSS classes are not loading properly until the page is tapped, which could indicate a rendering issue.
Just to confirm, are you using any speed optimization plugins on your site? I suspect there might be a plugin or some custom code causing this behavior.To assist you further, could you please share your System Status Report?
You can find this under: WooCommerce > Status
Please copy the report and paste it using https://pastebin.com/ or https://gist.github.com/ — then share the link here in your reply. This will help us better understand your setup.In the meantime
I would also recommend creating a staging site (a copy of your site), then switching to a default WordPress theme (like Twenty Twenty-Four or Storefront) and deactivating all plugins except WooCommerce. This will help determine if the issue is related to your theme or a plugin conflict.
For detailed steps on how to run a conflict test, you can follow this guide:

Let me know how that goes, and we’ll be happy to assist further.
