Currently, the only option for Thousand separator in DV is 12,34,56,789.xx. While this format works in countries like INDIA, it doesn't work in regions like AUSTRALIA who nationally use the thousand separation format of 123,456,789.xx. The current 1000 separator format is really annoying (not exaggerating) for business users in Australia.
The suggestion here is that OAC DV should either default the number formatting to the OS level locale settings or OAC DV should provide more formatting options for thousand separators to accomodate regions that don't use the current option.
