Trouble integrating Arlo Cameras

I have had Arlo Cameras up and running for over a year. I just bought Smartthings. I have followed all of the directions to connect Arlo to Smartthings. I have connected Smartthings to other smart devices in my home so I know that Smartthings is working. As for Arlo, on my Smartthing app I am able to connect to Arlo, but when I go to connect with the cameras they do not appear. I rebooted the system and that did not work. What am I missing?
