How can I fix the issue of Apple Music not being available on my Apple Watch after updating to watch OS 10.0.1?

Currently having this same issue with my series 8

He’s talking about the power button below the crown

I had the same issue on the latest version 10.1.1 but after resetting my Iwatch it worked. Push down the crown button to reset. It will unpair your Apple Watch you only have to go through the pairing process over again and music will work perfectly fine.

Basically all you have to do is hold the button under the crown then press power off and set your Apple Watch up again and if that doesn’t work then go to your Apple Watch settings then general and go all the way down and press reset then you’ll get it

I got this same issue on my series 5 updated software

How can I fix this?

Huh? When I push "down the crown button" It goes to Siri. Always has no matter which Watch, which watchOS.

Hot diggity dog! Works great. Much thanks!!
