As per the title all basic date slicers are stuck in the US date format and cannot be changed. My regional setting are set to UK and changing this around does not fix the issue.
We've been able to get this resolved in browsers using the various solutions posted elsewhere, such as https://superfarb.com/power-bi-customising-date-format/.
However, we've been unable to get the date formats for date sliders to display correctly for the language/regional setting in iOS browsers. Tested Safari, Edge and Chrome and all display in the US date format (ie. mm/dd).
I'm experiencing the same issue in Australia:
In my PBI desktop I have created a date slicer with the dd/mm/yyyy format. My locale settings for PBI and browsers are all Australia. When I published the reports they all defaulted to the US date format. Not a critical issue but definitely annoying as I'm getting a lot of queries on the date formats in my business.
@lonojee - what version of Power BI Desktop are you using? I think the date slicer issues were eventually fixed in after a couple of bad releases. I'm using July 18 and have a date slicer that is displaying dd mmm yyyy - it's OK.
@dgwilson I'm using the July 2018 version. As mentioned earlier my PBI desktop version is fine, but once I have published it online it defaults to the US version.
Any update on this?
I keep getting things "broken" every so often with this date format. All I can say is: I go back to the link TrevorL-at-dhhs posted and go through all those options again, until dates behave one more time. Yes, it´s annoying!
