It could be that the archived stories have been moved or deleted for some reason. Or perhaps you don't have the proper permissions to view them. Try reaching out to the platform's support team for clarification.
It could be that you don't have the right access permissions or your account settings are preventing you from viewing them. Check your settings to make sure everything is in order.
It could be that the archive settings were changed or not properly configured for that specific year. Or perhaps the data was lost or corrupted somehow.
You might try looking in the settings or menu options of the platform where you expect to find the archived stories. Sometimes there's a specific tab labeled 'Archives' or something similar.
