iOS Microsoft Intune MAM

Ask questions about the cause of the error when registering for iOS Microsoft Intune MAM and how to fix it.
I am using Objective-C.
MSAL authentication is used.

Error content: Each error occurs in two users.
error code-203
error message-The operation failed because the SDK could not access the user’s AAD token. The application should prompt the user for credentials to refresh the user’s AAD token.

error code-225
error message-The account is licensed for Intune but is not targeted with MAM policy.

I need help.
