Anyone else struggling with Reef's learning curve for complex formulas?

I've been using Reef for about a month now and it's fantastic for basic data cleanup, but I'm hitting a wall with nested conditional logic. The AI suggestions work great for straightforward tasks, but when I try to automate something with multiple IF statements across sheets, it either overwrites my existing formulas or suggests something that requires heavy manual tweaking. Am I missing something in the settings, or does anyone have workarounds for this?
