Samsung S25 Ultra Notification History duration

[October1]

Hello,

I have used S Ultra series Samsung for long time

I always have NOTIFICATION HISTORY saved for 24 hours, no changes in setting.

However, since Samsung 25 Ultra, I noticed that the notification history has an issue .

it only show notification history for a few hours, not 24 hours anymore in the "24 hours notifications"

I reset all notifications and tested, I turned off and on notification history. it is still the same. 

I can see the notifications on "recently dismissed". and in "24 hours notifications" for a certain period of time less than few hours. I m not sure how many hours, but about 6 hours when I checked again, they all disappeared, and looked like, I dont have any new message apart from weather apps and system notifications.

If any solution can be found, that would be great!

Thank you!
