Accounts package does not work on mobile device

Hi,

It seems Account’s package’s loginWithPassword does not invoke its necessary callback on a mobile device (I tested on iPhone 6). It works fine on a simulator and on mobile web version. Then I found this question on Stackoverflow that I need to pass in --mobile-server param in order for the package to work. This solution works with *.meteor.com sites, but not with others like something.com or 107.123.123.123.

Did anyone else encounter an issue like this on their mobile devices? I’d really like to know why login doesn’t work in an app, but in the web version.
