I see. There are instances that it doesn't work properly on the phone that's why we are suggesting to make use of a computer browser to do transactions, viewing invoices and other stuff since not most of the time that the software or the same like this is supported on the mobile phones.

As for this, we actually don't have a control especially when it comes to mobile devices since not all are supported. We advice that whenever you view the invoice, it would be best to use a computer browser for this.
