iOS Facebook SDK Login Failure after Deleting Facebook Account and Restoring it

I am using the Facebook iOS SDK to allow users to log in to my app. This has been working flawlessly until I disabled and re-enabled my Facebook account during testing. Now, I can still login through my website using the Facebook login but not the iOS Device. I am getting the following error:

  <h1>OAuthException at /login/facebook-session</h1>
  <pre class="exception_value">The access token was invalidated on the device. (error code 190)</pre>

How do I fix this on the device? Can I have the App ask the user to validate the device for Facebook integration again?

I've read this post, but there were no resolutions there: Facebook posting procedure fails with error "The access token was invalidated on the device"

Thanks!

Do this to clear the token and then it works:

    // Ensure facebook is logged out
    [FBSession.activeSession closeAndClearTokenInformation];
    [FBSession.activeSession close];
    [FBSession setActiveSession:nil];
