Facebook form tab not working on mobile devices

I have gone through this process for my form https://www.facebook.com/SLYGNSW/app_684336108254110

but when I check it on my phone it shows that  "The page you requested was not found". Please help.

Hello slygnsw,

Please be noted that Page Tab apps are not supported on mobile devices by Facebook's Platform: https://developers.facebook.com/bugs/435173473172584/ 

A workaround for now would be to use third party websites that offer a mobile version for tabs. You can also your page direct URL as well. Please check the following guide and look for (FAQ - 1. The page tab does not appear on mobile devices?) section:  http://www.jotform.com/help/82-Adding-Form-to-Facebook-Custom-iFrame-App

Thank you!
