I apologise in advance if this been asked before, but I have spent 2 days googling/trying different methods to no avail.
- I have built an app for a client.
- It works fine on desktop. No problems.
- When I click on the link to the app on my iPhone iPad, its says "Page not found"
Client page (where app 'Win With Parade' has been added: https://www.facebook.com/ParadeSwindon
The app in question: https://www.facebook.com/ParadeSwindon/app_155622657928426
I have tried Authentication 'Native/Desktop' with no improvement.
I have attached a screen shot of the setup, again works fine on desktop, just fails in iOS Facebook app.
