It just started happening after I updated yesterday. And again, it only happens if the first thing I do upon program load is try to access a Customer Ticket from the Customer Tickets screen by way of a custom Navigation Menu, not from the default Navigation menu.
Here’s some screenshots.
I load the POS fresh on one of the 7 terminals we have. Tickets have been entered elsewhere on other terminals. A staff member goes to a terminal that hasn’t been used yet and goes to the Custom Navigation Menu which has a button that goes directly to the Customer Tickets screen.
They try to click on a ticket and get the following error:
