Squarespace not recognizing FB and Instagram orders

Facebook meta is giving me a notification saying that my customers order cannot be processed until recognized by commerce manager. I had everything linked and working and then the first order came through (but didn't until I found it on FB meta), and there is no way to manually process this order. I need to know how to fix this. For the time being I've disabled the store via FB and Instagram.

Did you ever find a resolution to this issue? I am getting the same message, and some angry customers. 

Meta says Squarespace is to blame.
