Why can't I see my Form on my Facebook Mobile App?

Hello I need help!

I can only see my facebook form through desktop but unable to do so through my FB app.

I have checked your Facebook page and I can see the form does not display on the mobile version of Facebook, for example, this is present when you load the page in a desktop computer: 

And it is not there in the mobile version of Facebook: 

I think this is intentionally in the Facebook app since you are practically loading another webpage, which is the form in this case, so it would be more work to do for the app, so instead of showing the form as the desktop version they only show the button "Book Now" and it redirects to your form, but it does in an external page. 

So this is how the app for mobile works and there would not be much to do to show the form there.
