0Auth2 Stuck on Permission Page - swift

Question

Currently having an issue with 0auth2 permissions. It keeps on getting stuck to this page: Stuck101. It doesn't crash, just remains completely dormant.
The debug console shows this:
[Debug] OAuth2: Initialization finished
[Debug] OAuth2: Looking for items in keychain
[Debug] OAuth2: Starting authorization
[Debug] OAuth2: No access token, checking if a refresh token is available
[Debug] OAuth2: Error refreshing token: I don't have a refresh token, not
trying to refresh
[Debug] OAuth2: Opening authorize URL embedded: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?state=7A3CEE60&response_type=code&scope=openid+profile+offline_access+User.Read+Mail.Read+Calendars.Read&redirect_uri=KTracker2%3A%2F%2Foauth2%2Fcallback&client_id=584bb6db-5b71-4d7c-9015-fab8a9dfae4c
2018-05-09 04:49:47.198828+0100 KTracker2[8281:180974] [App] if we're in the real pre-commit handler we can't actually add any new fences due to CA restriction

func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

I also have KTracker2 added in the plist files
Any ideas to why my app lies dormant would be great. Thanks a bunch.
