Hey Tane! We should make this more clear, but the preview you get when running a WebContainer projects is not shareable – in this way WebContainers work more like localhost projects: unless someone doesn't run the thing on their machine, it won't show anything.I realize it's not perfect for sharing demos directly 
What I usually recommend is to share the IDE URL instead of the preview (so sth like https://stackblitz.com/edit/vitejs-vite-whwnjp instead of https://vitejsvitewhwnjp-2luh--5173--ba0db7b1.local-credentialless.webcontainer.io) – this way it will open and run in another person's browser just as it does on your end.
Again, I know it's not ideal and apologies for the confusing ux, we hope to make sharing previews directly possible in the future.
