v0 showing "This chat is private" error during generation

Hi! I am trying to test v0 after seeing some great videos on YouTube. However, I am not having any luck getting it to output anything at all.

When I prompt it, it thinks and thinks and starts to output, and then suddenly the whole screen goes blank and all I see is:

This chat is private. Ask the owner to update this chat’s sharing permissions.

How can I start using v0? I tried a few more times with no luck.
