So I've tried it a few times now, airplay to the watch works but intermittently. Sometimes it works and sometimes now haven't been able to figure out why
You can play music via the Watch's inbuilt speaker, from glances play some music using the remote and then go to settings and press the Airplay icon and choose Apple Watch
I believe it sometimes takes a couple of hrs to change status or it just could have been a test authorization. Mine just change to Preparing for Shipment
I ordered my 38 Space grey (2 watches) on the 8th of May, first got a date range of 1-17 June and last week it changed to Jun 10 - 23.
Did that happen to anyone else? Although the 2 extra bands I ordered have shipped.
