UX/Sign Up Form
1. There is no validation as-you-type of the credit card fields
2.. When one press create account nothing happens if you didn't entered for example ZIP code. Nothing, and you do not know what you did wrong.
3. After entering the ZIP button didn't worked, was disabled.
4. In one attempt captcha expired, I clicked it, but the button was disabled again
5. Feedback after clicking the create button is very bad, one small poor animation.
6. A bit frustrated I entered wrong phone number on account activation, but then I faced the screen in attachment.
