Didn’t show on Chrome or Safari for me.
I was doing it on Chrome through my phone & didn’t get the drop down either, although thinking about it I think I have had the drop down on other sales.
I’d tried all formats dd//mm/yyyy & dd/mm/yy and on the form I only had the option to ‘apply’ rather than ‘submit’. Very odd.
Anyway, all sorted now albeit in 2 transactions.
Every time there’s something different. Keeps us on our toes I guess!
