A. Open the Fambase app, go to 'Settings', then 'Notifications'. Here, you should see options to customize your notification preferences. If this doesn't work, try clearing the app cache by going to 'Settings' on your device, selecting 'Apps', finding Fambase, and tapping 'Clear Cache'.
B. If the above steps do not resolve the issue, check your device's overall notification settings. Go to 'Settings', then 'Apps & notifications', select Fambase, and ensure notifications are enabled.
