WhatsApp Group Notification not displayed on Lock Screen for Samsung Mobile

[SVK]

From last few months I am facing this strange behavior on my Samsung S20+ regarding group notification for WhatsApp messages. For one-to-one messages, notification is displayed on lock screen and WhatsApp icon is also visible on AOD. But when message is received in some group, I only hear notification tone, but no notification on lock screen or AOD. Sometime If I slide finger from top to bottom on lock screen, then notification is displayed.
I check all notification settings in WhatsApp as well as Notification settings. The settings are same for individual messages and group messages.
Anybody with Samsung or other handset observed this behavior?

Seems to be working on my M31. Got a few messages a few minutes ago & it was visible on the lock screen.
Only odd thing was Samsung pay had its panel at the bottom of the screen but it disappeared some time back.

Check the notification settings of Group Notifications. 'Lock Screen' options should be set as 'show content'.

@Nishant as I mentioned in my first post, my Message Notification and Group Notification settings are exact same, and same as you mentioned in screenshot (except I have kept Vibrate enabled). Lock screen is set to Show content for Group Notification as well.
If I have single message and group message received, then both are displayed in Lock screen notification. But if only Group message is received, nothing is displayed on Lock screen.
Only after I unlock phone, I see WhatsApp symbol at top indicating I have unread messages, and by pulling down notification can seen.

Pretty strange then. This is working absolutely fine on my S21.

Just to cross check that particular group is not muted?

@igloo group is not muted.

On OnePlus 7 I do not see this issue, only on Samsung I am having this issue.

@Sushubh also faced similar notification related issue on Samsung S10 Lite for WhatsApp or some other app?

My thing was about waking up display.

Oneui 4 I think adds the option for all apps iirc.

Recent observation.
When I get message in any group, nothing is displayed in AOD and Lock Screen. After I unlock phone, I see notification icon at top.
if I Swipe down to see notification, and Swipe right on particular group message, Settings option is displayed. After opening that setting, I see that particular group is categorized under Silent Notification, and notification is set as "Silent" (obviously). I changed it from Silent to Alert. Then locked phone, and notification was visible on Lock screen.
But after message was received in some other group, it was again not visible. I followed above steps and same result, it was visible.
I wonder whether I have to toggle that setting for every group message received.
