Hey there! Shamoon here. The 30% Apple transaction fee typically applies to digital goods and services purchased through an app. However, for physical goods like those offered by Park Mobile, this fee may not be applicable as it falls outside the scope of digital transactions. Park Mobile likely operates as a platform facilitating payments for physical services rather than digital goods, thus avoiding the Apple transaction fee. If you need further assistance or have more questions, feel free to reach out to me at +923317587583. I'm here to help!
