Since update to 4.0 companion app no longer starts

[twain47]

Hi,

I updated my watch to the latest version and now the companion app on the phone is not started.

I've attached it to the studio.fitbit.com to confirm. Console logs from 2 rounds of start/close of the app:

[11:49:12]Sideload successful!

code from the start of the companion app:

import * as messaging from "messaging";

console.log("Companion Started");

messaging.peerSocket.onopen = () => {
  console.log("Companion Ready");
  sendMessage();
}

Can you try restarting your phone. I've seen an issue like this directly after a firmware update.
