Our application can be accessed throught mobile and web. We require verification of email. We will send email with link for activation through web and code for mobile app. I have question regarding this use case
do you thing some users would like to register throught web and finish the activation via mobile, I can imagine the other way round is fairly possible.
in mobile app after the registration dialog the dialog awaiting activation code will wait until the user will enter the code or will dismiss the dialog. In case of dismiss would you prefer to have possibility to invoke special dialog for entering the activation code or do you prefer to create new registration from scratch.
Dialog awaiting activation code will warn user in case of cancel so he will need to create new registration afterward.
