I just received my Ultra and I'm unable to link it with my Roku.com account. The error is "We're sorry, the email you provided isn't working." I tried dozens of times, confirming every time that the address I'm entering on my TV is identical to my Roku.com account email. WTF?!
Never mind. After an extremely unhelpful service chat I decided to return my Ultra for credit. Here's the story in a nutshell. (1) I created a Roku.com account with an email address through my email forwarding service, ***@liamekaens.com. (2) I tried dozens of times to use this same address when setting up my Ultra, always being told it doesn't work (see title above), and I even tried a different address on that server... that's strike #1 (3) During the service chat I was asked to try an email address through a different email server, but there's no way (I can find) to change the Roku.com email address... that's strike #2 (4) I finally tried a yahoo.com address for the Ultra setup and got an activation email, but I was asked to create a new Roku.com account, which is ridiculous since I already have an account (5) Service said my liamekaens.com email server must be down, but I sent them a screenshot of a Roku Community email I received today at that address, so I asked them to email me so I can respond to prove my email server is up and running, but they said they can't send emails... that's strike #3. (6) This company has little tech savvy so I'll avoid future headaches by returning my device and moving on.
