We use Quickbooks Desktop- Manufacturing & Distribution 20.0 

I have spent over 8 hours on the line with support and no one can give me an answer.

In November we noticed that our online invoice payments coming through Merchant services were not being automatically applied to the customer account as they always had been.  

Since that time we have had to manually record all the payments coming from those customers paying through the "pay now" button on the e-invoice.  

I would love some guidance as this is creating a lot of extra steps and room for error.
