How do I stop my date and time format from going back to US-style

[Olivier Kraft]

Hi,

I've selected English UK as my language in Atlassian/Trello, but the date and time format in Trello keeps going back to US style (October 5, instead of 5 October).

The format briefly changes back to UK style if I switch my language to US and then back to English UK. But this only lasts a few days, before the date format reverts to US style.

Could you please advise how to keep the date format in sync with my selected language?

Thanks,

Oli
