There may not be a notification.

There is a situation like this, that is, there is a check mark on the application form to agree to the downgrade (not the original words, anyway, it is a similar meaning, that is, the card type of this level cannot be approved, can the card be downgraded? If you choose to apply for a card at a different level), if you choose to agree, it will be judged based on your credit status during the review. If it does not meet the current level of card type, you may be lowered to apply for a lower level, and you will not be notified specifically.

Another situation is that you did not agree to lower the level on the application form, but the bank found during the review that your situation does not meet the application conditions for this level of card, and will ask during the phone credit review. Can you handle low-level cards?
