Question Facebook Dating Notification

Just a few questions.

What phone do you have?

What have you tried, other than checking the settings?

When you go into the app do you have notifications waiting?

Have they ever worked or has it been this way from the start?

Do you get other FB notifications?

With such limited information it is difficult to say for sure but let's start with the basics and after we get your answers we can look at other things. First let's clear the app cache. Settings>Applications>Facebook>Force stop>Storage>Clear cache/Clear data. You won't lose anything clearing the cache. Clearing the data for FB will default any settings you've changed in the app and you will have to change back to your preference afterwards, but all of your FB data is stored remotely and the app is only an access point. I would also clear the data for Meta and Messenger since they are related to FB. At this point I would usually say restart the phone and test. You should still restart but you may not be able to test this since it is dependent on someone messaging you, I assume.

Since we don't know if you are receiving other FB notifications I don't know how useful it would be to clear the system partition cache but it can't hurt. Without knowing what device you have I'll offer generic instructions that work for ~90% of devices. Power off the device>while restarting hold the volume + and the power button until the splash screen appears>release the power button but continue to hold the volume + button until the phone is fully booted>use the volume buttons to navigate and highlight Clear Partition Cache and use the power button to make the selection>when complete use the Reboot option to restart the phone.

Let us know what you find and we'll go from there.
