Our app ID is 708064914;
When we transferred an app with Sign in with Apple function, and request the REST API to get transfer_sub, approximately 25% of the requests return error responses such as:
{"error":"invalid_request","error_description":"User not found."} or {"error":"invalid_request"}
User 001700.6b50fa0cdf564b4f83e3ac6b8dfb9a9b.1205 received the first error;
User 000908.523b85e1dd704d808dbfac55425c5a7b.1916 received the second error.
Here's the English translation: We want to understand under what circumstances these errors occur. Since we have already transferred once before, this is the second transfer. The "User not found" error might be related to IDs from the original team. However, we don't understand the meaning of the second error type and what circumstances might cause it.
