Facebook login keeps failing
Before starting, a very similar question was asked recently, but I was facing a couple of other issues, and wanted to add some context.
Basically, off late, I witnessed that the login with Facebook feature in my Android app would keep failing for new users (who hadn't authorized the app before). However, this wasn't a recurring issue, so I sort of ignored it. But now this seems to be happening far too regularly.
I am absolutely sure that no changes were made in the app's settings locally or with the FB settings page.
There are 2 variants of the error -
a simple "Error occurred. Try again." And another which gives a much more detailed output.
However, I'm not sure of what changes do I need to make, if any. Would really appreciate any help with this.
In your facebook developer account try going to your application settings-> advanced and select Native/Desktop in Authentication. This should remove at least the first error.
I created a new application today and I'm also facing the second error. But for the older projects it works.
