Can't connect to "Secured Network" via WiFi. Get stuck at a Lock screen

- OS: OxygenOS version 2.2.0 - Android version: 5.1.1 - Phone Model: ONE 2005 [OnePlus 2] (Build number: One A2005_14_151211) When I connect to a Secured Wifi network that requires that I "Accept" some sort of agreement, normally I would click on "Sign into Wi-Fi Network", which pops up on my status screen and then I would "Accept" the agreement. Now when I click on "Sign into Wi-Fi Network", all I see is a screen with a big circle around a lock. I can't tap on anything on this screen, except exiting out. If I exit out, I am taken back to my home screen and not connected to the internet. All that happens is that "Sign into Wi-Fi Network" appears in my status screen again. If I click on it again, I go right back to the lock screen. Upon further investigation, I saw Option Dots on the top right on that screen with the big lock on it. I tapped the Option Dots, which brought up a menu with the following 2 options: 1. "Do not use this network" 2. "Use this network as is" I selected "*Use this network as is*" After doing this, I am taken back to my home screen as before. This time, the "Sign into Wi-Fi Network" option is no longer on my status screen and I am still not connected to the internet when I tried to access my email, Facebook, etc. Any insight would be much appreciated.
