After I sucessfully activated the first Roku Stick destined for Washington State, I remove all the componets, including the power cable and placed them in a bag to keep them separate, so not to confuse them with the other 2 Roku sticks.
When I tried to activate the 2nd Roku Stick destined for Washington State, I used all the components that came with the 2nd box, including the power cable. Since I was not reusing the same power cable for each activation, I'm not sure why it didn't work.
Before I go through the process of unlinking the 3 Roku devices and doing a factory reset on them, is there anything else you can think of that I can try?
Thanks.
