When I email receipts to my account to scan & pair up with transaction, it changes the date format to mm/dd. This then does not match the transaction date & adds another.

I acknowledge the effort you've already put into confirming your default date format, Ray. I know that manually adjusting the dates on scanned receipts can be an extra task.

Since you've verified that your date format is set to dd/mm/yyyy, but the system switches to mm/dd/yyyy during the scanning process, I recommend reaching out to our live support team for further assistance.
 

While I'd like to assist you directly, our live experts can investigate this issue further and ensure your uploaded receipts show the correct date format.

In the meantime, you can continue using your current workaround of manually adjusting the receipt dates if necessary.

Please let us know if you have any further questions. We're always here to help.
