When posting the transactions from the Square App integration, I get the following issue: We couldn't Undo the transaction(s) due to "Uncaught in complete callback". Check account mapping in advanced settings and try again.
But it doesnt say what to check or what is the issue. Also, when posting the credit card transactions, is duplicating them multiple times.
Quickbooks support has not been able to help and keep referring me to Square, even thou Square information is correct and the app was developed by Intuit.
