Hello GraysonP11,
Thanks for using Apple Support Communities, it's great to have you here.
It sounds like parental controls have been set up on your iPhone, based on the your description of the issue. You mentioned that you looked into that but since we're not sure exactly where you looked, we want to share some resources below that should help you get this resolved:
If you've confirmed that there are no parental controls on your device and that you aren't part of a Family Sharing group where controls may have been implemented, then we would recommend restarting your iPhone and trying to install any potential updates. To restart, begin here: Restart your iPhone - Apple Support and to update your iPhone, start here: Update your iPhone or iPad - Apple Support.
Thank you for being a part of the community here. We hope this information helps!
Best wishes.
