Hello,
We recently transferred our iOS app from an individual developer account to a corporate account. By following this guide (link), we successfully obtained the transfer identifiers for all our current users and have stored the data fetched from Apple.
Now that the transfer has been completed for about 10 hours, we're attempting to remap the old identifiers to the new ones using this guide (link). Unfortunately, all our requests are returning an 'invalid_request' error. I've noticed others have faced the same problem, but I haven't found a solution yet.
Can anyone help me resolve this issue?
