I'm having the same issue. I have my profile completed, however the "verify phone number" button does not seem to be working. I have tried multiple browsers and cleared my cache, no luck.
I just registered, it follows with "Next, you'll be asked to verify your phone number for added security."
When I get there, I enter my number, the field is green to click, but nothing happens, and I can't move on.
I have entered all the information to complete my profile however I am having trouble with phone verification. I am currently staying in Ukraine however I live in the United States and have United States citizenship. My American phone number cannot receive text messages from abroad so I am unable to verify my phone number via text message. Is there any other way I can verify?
