Netflix says 'Sorry, this offer cannot be redeemed on this Netflix account.'

If you see an error that says

Sorry, this offer cannot be redeemed on this Netflix account.

It means that either:

• you have already redeemed the maximum number for this particular offer on this account.

• you are an extra member on someone's account and are ineligible for this offer.

To fix this issue, you can apply the promotion to a different or new Netflix account.
