Thank you for your feedback.
Please note, Bedtime mode has been moved to Bixby Routines :
You can now manage Bedtime mode in Bixby Routines instead of Clock. Bixby Routines lets you automate more actions when it’s time for bed, like turning on Do not disturb or changing other settings on your phone.
We hope you will try this feature and report any errors you encounter.
We appreciate your contribution to the Beta Program.
