Content display and layout issue

Hi Team,
I have installed your plugin and made our android app live at google play store too, you can find it at https://play.google.com/store/apps/details?id=mobi.androapp.swadse.c3499
But I am facing some issues as mentioned below:
1) Home shows smaller (half height iframe with two images only) iframe in half of the height of my mobile and rest part is blank. How to increase the height so that it will spread on whole mobile heght? I tried change height in css but not worked for me.

2) Category shows only title of category and no items/content. Please check the same at Category > All Product, you will only see below content:
Shop
by swadse – 1 month ago
However, it should show products in that page as showing at http://swadse.com/shop/, both link are same.

3) I found a bug that user has to put his details again and again even if he logged in or already bought one product, by default it should show earlier entered address or fetch from users information.

In addition, I would like to know whether payumoney payment gateway will work on your adnroid app or not? I am using the same at my website http://swadse.com and same is working good.

thanks,
