This is so frustrating. I have a ton of orders to process, and unfortunately I rely on this API to tie into my inventory to generate pick lists. At least for future reference I know I need to have a backup plan in place, but that does me no good now. I have refreshed my access token a few times to see if that has any effect, but nothing. And also still no acknowledgment about this error on the API status page, so as far as I know they aren't even looking into it yet.
