In my TS-453A, I have a continual Notice Board about firmware update notifications being disabled. No way to manually clear this Notice Board, and clicking on it brings me to the Firmware Update configuration page and starts creating a new rule for notifications.
But the notification rule certainly exists (I have re-created it several times, to be sure)
Only changing the Firmware update option to “do not notify me, do not automatically update” clears the notice board. Even setting it to Automatically install will keep the notice board there.
You are getting this because you have asked the system to notify you but you don’t have any method of notifying you set up in Notification Center. So it will never clear.
If you don’t want notifications about firmware updates, then change the option to “do not notify me.” If you want to receive notifications, then you need to set up a notification method in Notification Center - via email, Push, SMS, etc.
But I do have an active Email notification method and firmware rule setup in the Notification Center? I get email notifications when I change the name of the rule, etc. so it is working
