The main issue I have with date format is when receipt snap is reading/processing Canadian receipts. Since many receipts in Canada either do YY/MM/DD or DD/MM/YY, I have receipts that are interpreted as being from 2012 when the 12 was actually December; I even have one that’s post dated to 2023 because of this same issue.
it’s easy enough to address when scanning one receipt, but to do it if you have dozens to scan is soooooooo frustrating.
