Alexa not adding devices

I added 2 switches to Vera. I go to Alexa app and try to discover new devices and it says none added. I go to Your Smart home skills and click on Vera Control. All I get is a white screen.

Go to, login, then in the upper right corner click on the drop-down menu and choose Manage Alexa.
From the Manage Alexa Page, select the two new devices you’ve added to your Vera. After you’ve selected these devices, go to your Alexa App and run Discover devices again.

This procedure needs to be done everytime you add new devices to your Vera.
