My repeated notification options don't work at all! If I don't look at my phone I won't know I have texts, calls, etc. I'm updated on my software etc, I don't have do not disturb on either. I don't know what's the problem. I can't find any answers. I have a note10 plus
The function may be turned off after software update. First, go to the settings below to make sure the "notification reminders" feature is turned on.
Setting > Accessibility > Advanced settings > Notification reminders
i hope this was helpful.
