We almost rewrote our whole backend before realizing the UI was just confusing

A while back I noticed a steady stream of bug reports coming in every week. My first instinct was to blame tech debt and start rewriting logic. But when I took a step back and walked through the exact screens users were complaining about I realized they were just guessing how the feature worked because our error messages were useless. We spent a few days fixing the empty states and making the onboarding clearer and the complaints instantly dropped. It made me realize how easy it is to blame the code when the real issue is just poor design communication.

Do you track why users get stuck or do you jump straight into code fixes?
