Notes on my iPhone keel crashing

The notes app on my iPhone keeps crashing. I tried restarting my iPhone, disconnecting from Wi-fi… Nothing changed. I remembet having the same problem few years ago. I remember finding a solution… something with typing in some kind of code again… but I can’t for the life of me figure out what the exact procedure was! Anyone has any idea how to fix this?

Any ideas? I tried everything I could think of. I know I had the same problem years ago and managed to fix it, but I can’t remember how!

It’s alright, I finally managed to figure it out on my own… God, it was so frustrating! But Notes work now.

It would be nice if you told us your solution, just for people who have the same problem and will get to this thread in the future.
