How Worlds billing works

Worlds are billed per second of live session. The price shows next to Start before you begin. There is a minimum of 1 seconds even if you stop sooner, and a session stops by itself after at most 2 minutes.

When you press Start, the most the session could cost is set aside from your credits. When the session ends, whatever you did not use goes back to your balance.

A session is a live stream, so it does not appear in Library. If Worlds is unavailable when you press Start, you are not charged. Worlds needs a paid plan.
