It seems like Samsung disabled (or broke) this feature in the One UI 2.1 update. The feature has been disabled at the firmware level, so there is nothing we can do to fix it. Our best suggestion is to ask for the reintroduction of this feature on the Samsung forum. https://us.community.samsung.com/t5/Note10/Wallpaper-scrolling-not-working-after-one-ui-2-1-update/td-p/1211105
Unfortunately the bug depends on some Samsung firmware, because of this there is nothing we can do to fix this problem. The issue affects Smart Launcher, like any other apps on Play Store that displays info about alarms.
At the moment, there aren’t any other known issues on Samsung devices, if you find any, please report the problem to email@example.com
