I’ve been tearing my hair out with exactly this problem since iOS 16 was announced.
I’ve called and emailed Apple without resolution since the WDDC at the beginning of June 2022 😡
I’m now thinking of buying a “full fat” 2023 MacBook Pro 16 (M2 Max) for nearly £7K, but there’s no way I’ll spend this much on an Apple laptop without being able to join the Dev programme 🤷
