Date input field displays date in US format, but need normal one

[ArturasF]

Hello all, I am building an app and the date field is displayed like this:

I need YYYY/MM/DD format.

Google Sheet source is set to the Lithuania (we use YYYY/MM/DD).
AppSheet tables are all set to Lithuania.
Macbook settings are set to use YYYY/MM/DD.
I tried different browsers, and tried on my phone. Still US format.

You seem to be getting the dates in DD/MM/YYYY format

US format is MM/DD/YYYY

Anyway, could you also verify if your browser setting as follows. The example below shows for Google Chrome browser.

In your case, I believe the preferred language at the first place should be Lithuanian.
