Fixing GW Bedtime Mode Sync!

Here's how I got this to work:

First open up your Galaxy Wearables app, go to Watch Settings and click Advanced Features. Tap on bedtime mode and turn on the sync bedtime mode. 

Try bedtime mode on your watch. If it doesn't turn bedtime mode on your phone, then follow these next steps. 

Go to the Modes under Bixby and open the "Sleep" mode. Tap the three dots in the top right and delete it. Then go to the bottom and tap "Add mode". Then tap "Sleep". Configure your sleep settings to your liking. And then try bedtime mode on your watch again. 

This worked for me. Now when I turn bedtime mode on my watch, it also activates sleep mode on my phone flawlessly! 

It's so unnecessary to need to do all of this. Samsung should just fix the issue but hopefully this works for others.
