Because just a minute amount of time was spent on making animoji for poop face

I have no idea but it's something Apple can GREATLY improve upon. Seems like everything is done on Bluetooth alone. Makes you wonder why Apple puts WiFi in the Series 2 or Series 3 at all since it's not used for
WatchOS installation
Sync'ing Music.
So for those of you thinking if upgrading to AppleWatch Series 3 or 2017 iPhone consider the following.
Both AW S2/S3 have Bluetooth 4.2.
Bluetooth 5.0
@Apple; WHY the difference between these devices to STILL maintain a slow WatchOS update as well as slow music and data synchronization!? #&$&$($()$
Well at least I can NOW have multiple music playlists on my Watch Nike + S2.
