new v0 project
* very basic beginner app with a supabase connection
* the inline preview works just fine & executing database transactions successfully
* when i click the button to open the preview in a separate tab, the app fails in that separate tab complaining that the environment variables are missing

i am adding two screenshots: one showing that the env variables for the project are clearly set, and another showing the error when previewing in a separate tab

Hey, Avioing!

Appreciate you sharing this. 

I will pass it onto the v0 team right now, especially as this seems to have affected someone else as well: https://community.vercel.com/t/missing-env-variables/5527/.

Will loop back!
