I need you to help me reset my notes app password.

I’m using my new iPhone 8plus on iOS 11.1.1. And I’m trying to remember notes password but I can’t. I had set notes password on my previous iPhone 5s (iOS 10.3.3) around 10 months ago and I was using Touch ID before to unlock them. I’ve tried to reset password but it doesn’t work for old notes. I want to look through my notes again. There are very necessary for me. Please, do something with soft to make my dreams come true. Thank you!
