Sleep mode doesn't apply to my lock screen

[Members_GKdCCI9]

I just switched from a Samsung J6 to the A52 5G - with the J6 when bedtime mode was applied it would also apply to the lock screen. With the A52 this isn't the case. I'm not sure if my phone is glitching or if this is simply how the phone is set up.

Any advice? My phone is up to date and I've searched through settings multiple times not being able to find a solution (or perhaps I'm just missing something very obvious).

Thanks

@Simon-Jersey Unfortunately no change - starting to think it might just be how the phone is set up.

I got a response from support team and supplied screen shots. Waiting for further feedback
