Update — Free Tier Credit Refresh Failure This issue has been resolved. Monthly credit refresh is now functioning correctly for all free tier accounts. Affected users should find their credit balance has been restored to reflect the current billing period.

Free Tier Credit Refresh Failure

We're aware of an issue affecting free tier accounts where monthly credits are failing to reset at the start of a new billing period.

This issue was introduced as an unintended side effect of a recent update designed to prevent new account fraud, which implemented credit syncing across free tier accounts on the same device. In some cases, this syncing behaviour is interfering with the monthly credit refresh, leaving affected accounts showing zero available credits despite the period having reset.

Free tier users who share a device with another NZGrader account are most likely to be affected. Paid subscribers on Teacher Pro and Student Premium plans are unaffected, and their credits continue to refresh as expected.

We have identified the cause and are actively working on a resolution. We will update this page as soon as a fix has been deployed.
