cannot play on a call not established yet

[seven1240]

sometimes I get an error when I immediately call play on a connected call. the call is successfully connected but looks like the state is not updated before I run play, and there's no function to wait for the state. Adding a sleep helps before play.

Error connecting call: Error: Can't call play() on a call not established yet.

and the peer.id is not available

    const peer = await call.connect(plan);
    console.log("B", "Call connected! id =", peer.id);
