Can't upload custom gamerpic

well typically changing the age of your account after setup doesn't affect your account age fyi

Once you setup.your Xbox account you are asked for your age

If you entered it wrong during that time there is no recourse

Try performing a hard reset EXACTLY like this. Hold the power button on the console for 8 seconds or until the power shuts down completely.
Unplug the power cord from the back of the console for 5 minutes.
Plug the power cord back in and restart the console.

I hope this information helps

Did as you said but it still wouldn't update, I'll try restartig my phone and unistalling the app. Thanks for the help though!

Not stupid at all.

Perfectly reasonable that under 18's can't upload a custom gamerpic.
