Date format is ignored when displaying birthdays
I chose in the outlook.com settings to show dates as 01/09/2021 for Sept 1st (European DD/MM/YYYY format). However, this setting does not appear to be applied when displaying the birthday of a contact - I see 8/1/1950 for someone who has their birthday on August 1st. When I edit the birthday, it shows correctly as August 1, but when in the normal view, it swaps the birthday to the US format MM/DD/YYYY

It is very confusing, particularly when the month and days are less or equal to 12!!
