As per your concern, we would request you to kindly perform the following steps to resolve your issue.
Reset the device Settings: Settings > General Management > Reset settings>Reset all settings to their default.
Manage app notifications: Settings> Select the Apps menu> Choose one app that you want to manage from the list of all the installed apps.> Notifications> Step 4. You can activate or deactivate notifications at once by tapping the switch of Show notifications, and you can also select the features you want to receive notifications for, e.g. Samsung Galaxy app. Note: The features of the notification setting may differ from each app.
Keep your app updated: Tap on Google Play Store app or Galaxy Store> Manage apps & device> Apps available to update> If you want to update apps individually, tap See details and then tap the Update button next to the app you would like to update.
In case the issue still occurs, kindly report the problems with a log file. To share a log file, click on the Samsung Members Application (Open Samsung Members Application > Support> Tap on error report > Type your query > Send).
This is not a customer support post. It is to show how Samsung would like to shove ads in our face. Those steps aren't gonna help unless you specially revert this change. I don't care if youu don't, since this will be my last galaxy.
