Hi cruze007, can you please check once in the Settings > Tap om lockscreen > Tap on Always On Display > Swipe through the clock styles > You can select and change the clock style of your choice and Tap Done.
You can use Edge clock during overnight hours to get a quick glimpse of the time without having a lot of light and not using the full AOD screen. Widgets and notifications aren't shown when the Edge clock is displayed.
