I 'm running Survey 123 for Android on a Android 7.0 handheld device. When the App is launched, I do get prompted for my AGOL credentials. Once entered and busy signing in, the App remain static and stuck on the authentication process indefinitely. (screen spinning circle). Have anyone else experienced this before? Any help or idea how to get past the authentication step will be appreciated. Just to mention, all the prescribed URLs have been white listed in the firewall..
