Backed up settings couldn't be restored successfully. Tried both from Samsung Cloud and Smart switch.Some settings/menu link have been changed.Google Play service updates have issue.
Sleep mode isn't available. Although the DND is working but it can't be scheduled with sleep mode. Sleep mode used to be visible in the Clock app. Option for it is available but broken.
Hmm. You need leave beta program. Phone should reset to factory condition. All data will be lost.Even after leaving beta, if the phone doesn't reset, use Samsung PC Software to DOWNGRADE.
