The most miserable software experience I've had was trying to support a Microsoft BI system built with a no-code tool. It was all drag-and-drop and fill in the boxes. Instead of code you were left with an inscrutable XML file. It was nearly impossible to trace the flow from input to output, and even worse if you were trying to go backwards from output to input. Good luck to you if someone had a question about how a value in the database was derived.
