I'm using list builder v2 for Ipad and anytime an email with a .ca extension is entered it shows an error message "invalid email" .com extensions work just fine. I use my Ipad offline at trade shows for customers to enter their email contact.
.ca emails work fine from the browser.
Thank you for reaching out to us about this. We actually don't have any other reports of the ListBuilder app refusing .ca addresses so our internal team is going to research this further to see what may be causing this and how we can resolve it. That team will contact you directly within the next 4 business days with any information that they've found.
We really appreciate you letting us know that this is happening for you! If there's anything else that we can assist with in the meantime, please don't hesitate to let us know.
A quick update on this issue, seems line any extension less than 3 characters, ie: .ca, .eu, .co etc... will not work. Anything with 3 characters ie: .com, .biz works just fine. When I type in the 2 character extension I get this invalid email icon on the right of the email field as soon as I move to the next input field. 2nd tier support from Constant Contact sent me an email that they are working on the problem and looking for a solution. Crossing my fingers and hoping for a quick resolution.
