What really influences success with AES encryption in real-world projects?

Lately, I’ve been working on integrating AES encryption into my app and hit a wall understanding what actually helps improve success rates. Traditional advice just didn’t cut it, and I felt like I was spinning my wheels. Then I came across some strategies that focus on proper key management and implementation best practices, which made a huge difference. I found a lot of useful info on Reddit and YouTube about practical tips, and it’s honestly been a game changer for my project. Curious if others have similar experiences or tips to share.
