Correction needed to the lesson?

Question

Apparaître follows the same pattern as connaître for the passé composé, (aître -> u), so not an exception. See - https://conjugator.reverso.net/conjugation-rules-model-french/model-conna%C3%AEtre.html

EXCEPTIONS :

- apparaître (to appear, come to be) and derivatives

Answer

Bonjour David !
Indeed, here the "exception" with apparaître is that it's using être as an auxiliary verb in compound tenses (not avoir), but I understand your (and clearly others') confusion here, so I've rephrased the lesson to clarify this point.
Merci à tous et bonne journée !
