Sleep Mode timing issues

[kmbee]

When I had my S20, I had my sleep mode set to 2300-0600. When I would either a) turn it on earlier or b) turn it off, and turn it back on manually, it would automatically revert to the set schedule (waking up at 0600). I don't recall setting up anything extra besides the actual sleep time

I've recently upgraded to the S24 and if I want to do the same things as above, now the only options I have are guessing the amount of hours I want it off or turning it off manually whenever I wake up instead of it reverting to my set schedule and turning off at 0600.  Am I doing something wrong now? Did sleep mode itself change? It was really nice to be able to just turn it on and it would automatically adjust itself to my already set schedule. I have tried deleting/remaking the schedules, clearing data/cache, and rebooting the device.

Any help is appreciated!
