Arlo I tegration

I am trying to link my Arlo system to SmartThings. I see many posts about this but not what I am seeing. Everything is connected to 2 VMB5000 hubs. I have 2 Wireless video doorbells that work fine in ST, I have 2 Ultra 2 wireless cameras and one wireless indoor camera, all 3 of these show as connected in ST but when I select any of these 3 cameras I just a black video screen and all functions are disabled. Anyone got any thoughts?
