Currently having a problem with the date format on the cloud version.

I have tried this on multiple computers / on my phone and it works perfectly fine. But for some reason when my co-worker inputs a date on a date field, it reverts it to an american format. We want it as DD/MM/YY, But when he inputs it onto the Ninox calendar which pops up when you want to input a date, it reverts it to MM/DD/YY. Yet when he types the date it in, it stays as DD/MM/YY.

Just wondering if there is an easy fix for this, or is it a problem with Ninox?

TIA
