Kind regards, Erin Error 173 UidInPostBody: A request should not contain UID during POST operation Have had this consistently for the past week now and no fix yet, it is stobbing our customers/invoices being exported. I haven't been able to reconcile our marketplace accounts for a week (these are paid daily). Any assistance would be greatly appreciated!
