Hello @angerye:disqus, unfortunately Facebook doesn’t show apps on the mobile version, so you won’t be able to collect signups this way.
What you can do is to:
1. Post a link to your page/landing page, where you’ll collect the sign ups
2. Create a Lead Ad and connect it to GetResponse via Zapier. Pause ad, copy the Lead Ad URL and paste it on your Facebook Page as a regular post. Use Zapier to send new leads automatically to your account (this is a paid option).
3. Create a Lead Ad. Pause ad, copy the Lead Ad URL and paste it on your Facebook Page as a regular post. Then you’ll have to manually add the leads from an XML to your account. XML can be found in Ads Manager.
I know this isn’t ideal, but it works! 🙂
