How long does presence last on react native

[G2Jose]

I couldn't find this documented anywhere, is there a TTL on presence?

On the docs it says:

Presence is an object that each peer shares with every other peer. When a user updates their presence, it's instantly replicated to all users in that room. Presence persists throughout the remainder of a user's connection, and is automatically cleaned up when a user leaves the room

To test, I have code running on an android emulator and a iOS simulator. I close the app on either device, and expect to see the updated presence reflected on the other device, but I don't. Could it be that it's delayed?

Here's my code:

function usePresence() {
  const userId = useAppSelector(getCurrentUserId)
  const appState = useAppState()
  const presence = room.usePresence()
  room.useSyncPresence({ id: userId, online: appState === 'active' })
  return presence
}

export const Room = memo(() => {
  const { presence } = usePresence()
  return <SomeView /> // this view tells me if the other device is still online
}

Things I've tried:

1. Backgrounding either app does not clear presence
2. Fully closing either app does not clear presence
