Update — Logo Load Delay This issue has been resolved. The logo now loads correctly in line with the rest of the application interface.

Logo Load Delay

We're aware of an issue where the NZGrader logo is loading slower than the rest of the application interface.

This is a minor visual issue affecting the initial load of the app, where the logo may appear briefly delayed or absent while the rest of the page has already rendered. No functionality, grading, or feedback features are affected.

Impact to service is minimal. A fix has been identified and will be implemented prior to production release.

If you have further information regarding this issue, please contact us via support.

Update — Free Tier Credit Sync Delay Under Concurrent Sessions This issue has been resolved. Free tier credit balances now sync correctly across concurrent sessions on shared devices.

Free Tier Credit Sync Delay Under Concurrent Sessions

We're aware of an issue affecting free tier accounts where credit balances are failing to sync correctly when multiple accounts on the same device are running sessions simultaneously.

When two or more shared free tier accounts are active at the same time and spending credits within close intervals of each other, the syncing process is not given sufficient time to complete between transactions. This can result in credit balances being out of sync and not accurately reflecting the amount that has been spent across the affected accounts.

Users on free tier accounts that share a device with other NZGrader accounts and run sessions concurrently are most likely to experience this issue. Paid subscribers on Teacher Pro and Student Premium plans are unaffected.

We are currently investigating the cause and the full scope of impact. We will post an update here as our investigation progresses.

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.

Service Issue — Image Attachments in Student Submissions

We're aware of an issue affecting the processing of student work that contains embedded images.

When a submission includes images — such as diagrams, graphs, or scanned handwriting — those images are currently not being extracted and passed through to our grading algorithm. As a result, any content contained within those images will not be assessed, and the returned grade and feedback may be incomplete or inaccurate for affected submissions.

This issue impacts any teacher or student submitting work that relies on image-based content as part of their assessment response. Text-only submissions are unaffected and continue to process as expected.

Our team is actively investigating and working on a fix. In the meantime, we recommend where possible re-submitting work as text-only documents to ensure full and accurate analysis.

If you have additional information about a specific submission affected by this issue, please reach out to us via support.
