Update: This was tested on Goerli and Rinkeby. Same bug.
Hey, I didn't write logic to switch to testnets. You'll have to manually switch and refresh.  The believe the video is trying on Goerli. I don't have mainnet funds...
did you find a solution to this?
I had to enable full disk access. Might be a better & safer way.
