Samsung removed multi-user profiles feature in One UI 5 (Android 13)https://www.samnews24.com/2022/09/30/samsung-removed-multi-user-profiles-feature-in-one-ui-5-android...
I think they had problems with it and not time to optimize it propely. Maybe we will see it again with One Ui 5.1 or 6.
I can confirm - this feature was removed from One UI 5 Beta.
Have a good day!
