Sure, but in every single episodes, a lesson IS learned. They just dont take the time to make a “Dear Princess Celestia” scene like they used to. And that’s a good thing. Still,in my head-canon, they DO write the letters, but off screen.
“From this day forth, I would like you all to report to me your findings on the magic of friendship, when, and only when, you happen to discover them.” - Princess Celestia
They don’t show it because it’s boring.

You know, the whole “Lesson Zero” thing…
