Well you can try any of these to help with your problem as I try a number of them and sometimes I will be back playing that day.

Try the mobile webpage version(pink phone icon) if it doesnt work there then its them(nutaku or the creators).

If it does and you still get sent to the install page from the app, then see if your logged into the site from the menu button.

You can alway try deleting the data or app and reinstalling it(if you deleted the app) also you may need to login.

You can restart the device.
