New Notifications not vibrating on Lock Screen in Silent Mode


Dec 14, 2021
Just recently out of nowhere my phone (Redmi Note 11 Pro 5G) running latest ROM disabled vibrations on lock screen. They work fine when unlocked. I checked all vibration related setting but nothing fixes it. I have DND tuned OFF and Vibrate on Silent mode turned on. I have no idea what could be causing this as I did a full reinstall without restoring from backup and still it happens. I didn't do any system modification. I didn't root or install a custom recovery. Just the ROM and it was fine a week ago. Any help appreciated
Update: It doesn't vibrate only when the Notification Effect is on "Light up screen"
