Same here (Redmi Note 7 - MIUI 10.3.3 stable EEA). On miui.com thread with the same problem has existed for 4 years. Do not Disturb mode is useless in its present form. Notification after start this mode mislead, because it say that sounds and vibrations are disabled. Can you do something about it at last?
