Hi Jeff, Could you clarify what you mean when you say 'each time the service worker starts up' ? As in the 'install' phase of the lifecycle of a service...

Thanks for the info. Just to be on the safe side I have re-tested with DevTools closed in Safari. It still doesn't look `this._onSync()` is getting called at any point...

@philipwalton so will the fix of making the reply logic conditional on the registration succeeding fix the issues I'm having with Safari?
