Hi ChrisLouis,
Thanks for reaching out and welcome to the Community Forum.
Sorry to hear about your difficulties with downloading the invoices. I'm not sure if we are referring to the invoice sent by MYOB to users or invoices that users send to their clients. Currently, there is no way to bulk download invoices in both. Rest assured will raise this as a suggestion to the development team. If it's documents inside the In Tray we are referring to feel free to follow as gavin12345 has said. Also, if we are trying to manage our subscription or upgrade it I would recommend checking myaccount and managing it from there.
Let us know if you have any other questions or concerns.
Cheers,
Genreve
