Please keep us posted.
didn't the members app support team notify samsung US support about this notification?
they acknowlegded it's a cosmetic bug to be fixed in a future release.
Supposedly its coming from the Samsung Member app if you load the app tap the 3 dots in the right top corner then settings and then turn off the toggle for Diagnostics Notifications you shouldn't see it anymore
You can just pull the notification to the right select the settings button on left that appears. Select notification function that is turned on and it will turn off.
