Issues with Date Picker / Date Formats

[jslsmithyx]

Hello Community, 

I'm having some problems getting my dates to display / submit correctly using a Datepicker linked to a SharePoint List column configured as a date column. Searched multiple previous posts & tried many solutions but none have worked for me so far... 

Whatever I try, I cannot get dates to submit in a UK format to my SP list via a date picker. 

Dates displayed fine in the SP list itself (06/04/2020 = 06th April 2020) & initially displayed fine on the Datepicker, but whenever a new date is submitted it reverts to the US format & saves to the SP list as such. 

Things tried so far: 

Ensured SP Regional Settings are set to United Kingdom

Forcing the DatePicker format as "DD/MM/YYYY"

Setting language settings as "en-GB"

Setting the 'default' value on the Datacard itself as 'Text(ThisItem.'Target Release Date', "[$-en-GB]dd/mm/yyyy]")'

I can't understand where the Datepicker is getting the US date format from. The one thing I have noticed is when hovering over the formula in the 'update' value of the Datacard, the opposite date format is shown:

Any help would be greatly appreciated. 

Thanks!

Hi, 

I never managed to work out why dates are sometimes displayed in the wrong format on some devices - I think there is a local setting on those particular devices that overwrites what I code into the PowerApp.

I believe I made sure however that the dates were always submitted back to the data source in the UK format by configuring all my date pickers as below, with the circled element being the most important I think? 

So even though on some devices the date can be displayed in  the wrong format, the correct will always be displayed as it is always submitted back to the data source in the UK format. 

Good luck
