I'm developing web app and I share my contents using Facebook, the issue I'm facing is when someone clicks on the link posted on Facebook sometimes it opens using Facebook in app browser and that causes many issues.
Is there a way to prevent Facebook from opining my links and use the device default browser instead?
It is completely up to the user, there is no way to force opening it in the default browser instead. There is more information (and some answers) in this thread: File upload control not working in Facebook In-App Browser
