When a user sees an invoice on a mobile device the discount field is not shown. This creates issues since the total of line items do not match the amount due.
I got this dismissive reply from invoice ninja staff when I raised the issue on early December 2023. “We compress the visible data in the mobile views due to size constraints. The PDF is still available for download however.”
For me it does not make any sense do hide important financial information which has a direct impact on the total due just because someone is checking the invoice on a mobile device.
I use total discounts, defining a discount when creating the invoice and the discount section is missing.
I apply discount as amount not percentage (not sure if it makes a difference)
