Hi Sarah,
We apologise for any inconvenience. Unfortunately the website at the moment is experiencing performance challenges and bot traffic surge which is a general challenge for many public websites now.
Export function is one of resource consuming features and is under maintenance at the moment to optimise its workflow and also prevent it from being abused by malicious bots.
We will update on the website and the forum once this is resolved.
Thank you for understanding.
Kind Regards,
Mohamed
