Does the Duration setting right beneath Do Not Disturb affect it?
Hi janmatt, Thanks for the response. It would be helpful if you can share a screenshot. Please share a screenshot and make sure you are using the correct time settings. (Settings >> General Management >> Date and Time >> Set to "Automatic date and time")
Hi janmatt, Did the issue got resolved? Please try turning off the Bixby routines for a while and check if the issue got resolved. Most of the time this occurs due to the wrong time zone settings. So please also check the Date and time settings and set it to automatic.
