Airplane mode is not working on watchOS 6.0

Hello,

Yesterday I updated my iPhone XS to iOS 13.0 and Apple Watch Series 3 to watch OS 6.0.

When I turn on the Airplane mode on Apple Watch, I see it’s still connected to iPhone. It initially shows a red icon on the AW display that it has been disconnected, but in about 5 seconds, Apple Watch connects back to iPhone even if the Airplane mode is still active.

I keep getting notifications, messages, etc to Apple Watch. When I try to enable the Do Not Disturb mode on AW it enables the DND on iPhone too, but I need it to be turned off on iPhone and only enabled on Apple Watch.

I tried to power off both devices and it didn’t work out.

Could you please help me to fix this issue? Am I the only one who experience this issue?

Thanks!
