Why does the Field Service mobile Schedule card show US date format ("Aug 25") despite all-UK locale?

Hi all, in the Field Service mobile app (iOS), the Schedule tab appointment card shows the date month-first

("Tuesday, Aug 25, 2026") instead of UK day-first ("25 Aug 2026"). The times on the same card are fine (24-hour), so it's just the date ordering. 

Org Default Locale, the mobile user's Locale, and the device Region are all English (United Kingdom)

(ICU formats). There's no date-format option in Field Service Mobile Settings. 

Is this a known issue, and is there any supported way to control the date format on the card?

Thanks!
