Hi, is anybody else having issues sending revised combined shipping invoices? All I get is an error message in a big red box. "Something went wrong. Please try again later". I have tried every way possible on 3 different browsers. It is a multi piece invoice for a repeat buyer. This happened a couple months ago and it wasn't working for 3 days or more. I use this feature all the time. I lost good buyers last time and need to send this invoice ASAP. Thanks
