App rejected

I put admob ads in the app and uploaded it to play console to update, but this evening I got a mail saying your app has been rejected, how exactly did this happen, can anyone tell me?• What is the issue behind app rejection?


• And what should be done here, what age should be added, or leave it as it is?

Can You Tell me Your AppCategory

The meaning of this is Your App Is Made for everyone

But my app is rejected due to age target, and my app doesn’t contain any adult or inappropriate content.

Just set age target as 13
Or you can ask the user to add their own age
