Date formatting does not work

Hello.

This is bothering me:

I've read all the topics about date formatting (forum), and I do not know why, none of them work.

My scenery: DirectQuery > View > PowerBI

The date format is always in MM/DD/YYYY (english)

What I've Done:
- My Power BI software is in Portuguese (Brazil);
- I have already changed the PowerBI regional (File> Options> Regional Settings) to Brazil;
- I've already right clicked the Data column and changed the type to Regional Brazil;
- I've already tried using M-language (Date.toText (date, "DD/MM/YYYY"));
- I've already tried to separate the date into 3 parts and put it together in the correct order;

- I've already tried turning the column into the advanced editor like this:

     = Table.TransformColumnTypes (# "Column Added", {{"My Column", type date}}, "pt-BR")

Every time I convert the column to date, it returns to MM/DD/ YYYY, and days name in english.

And I need it to be DD/MM/YYYY

Can someone give a light?
