Ora, c'è già un question, che tenta di rispondere perché questa eccezione è in corso, ma francamente avrei preferito ora cos'è pancake.apple.com e perché restituisce un plist? A cosa serve questo plist e, inoltre, cos'è pancake.apple.com, ci sono altri casi in cui viene chiamato questo endpoint?

Ed ecco i contenuti in tutta la loro base di 64 decodificato gloria:

Questa è la "borsa"
