问了 openai 客服，答复如下：
Hello,
Thank you for reaching out to OpenAI Support.
We understand that you’re experiencing issues with subscribing to ChatGPT Plus under a new account due to your Apple ID that is already linked to a different OpenAI account. Unfortunately, once an Apple ID is linked to an OpenAI account, it cannot be unlinked or transferred to another account. This is a limitation set by Apple, where one Apple ID cannot manage multiple subscriptions for the same service.
To subscribe to ChatGPT Plus with a different OpenAI account (Account B), you would need to use a different Apple ID that isn’t already associated with another OpenAI account.
If you need further assistance or have other questions, feel free to let us know. We’re here to help!
Best,
Cri
