Clients cannot open the landing page on a mobile device using Facebook app?Asked by Postmarketing on May 04, 2015 at 12:29 PM
i've been recieving email from clients claming they cannot open the form on a mobile device, they claim that facebook asks them for their login information and then the link never loads
Mobile mobile device cannot open landing page
Are you referring to the mobile app of Facebook? Unfortunately, I believe the page tab is not supported in the Facebook mobile app that is why it is not being loaded.
But there's a workaround that you can use, you can try using the static HTML and add the embed form code there. Here's a guide that you can follow: http://www.jotform.com/help/82-Adding-Form-to-Facebook-Custom-iFrame-App-.
Do let us know if I misunderstood your concern.
