Hello! We have recently upgraded to Timeslips Premium and since the update I am having trouble approving prior invoices. I went into Accounts Receivable and then into enter a payment. The invoice that I need to pay says NOTE: Invoice G:21035 is pending approval. So I went to Bills and then to Approve or Clear Bills. There is nothing in the Proof or Revision tabs and the Undoable has several invoices in it but not this specific one. What do I need to do? I am about to start doing billing for April so I need to get this invoice paid so that I can move forward. Please help!
