Notification bug on iPhone 7?

I just got my iPhone 7 yesterday and I love it!!!!
My notifications aren't going to my phone.
I only get tweets and messages and other apps like Hatchi or Diceworld don't notify me on my phone.
I have to check on my Hatchi and the only way I know it's my turn on Diceworld is because the notifications go to my iPad.
I already restarted my phone and that still didn't help.
Is anyone having this issue and is this just a bug?
