Account Problem(sign up failure)

Hi.

I tried to sign up by iOS app with iPad pro 10.5 inch.

Regarding the sign up phase, I couldn't complete registration of my email account with the message "Something's not right. Please try again" even verify code was correct.

 And I couldn't retry with my this email address because message "Email address already in use" and I also couldn't sign in. 

Could you reset my email address account in Vuforia Chalk?
