I clicked for a trial... after a while I entered my phone, received an SMS, and no indication of what to do with the code I received. No place to enter the code in the web page, nothing.
Second attempt, and I got a place to put the code. Then, while I was filling up the registration data, the page refreshed and started all over.
Third attempt finally worked...
Not the best on-boarding experience, but hey it really is cheap!
Hm, no idea what would've gone wrong in your case. It sounds like something kept closing the websocket used to provide page interactivity or something?
