Hi @AeroConsultants,
Thank you for your kind words about our AI Chatbot! We appreciate your sharp eye, and we’ll take everything you said into consideration to continue to better ourselves 
Now, let’s address all your points one-by-one:
Form field heights do not match + Phone field display
We looked into the first two issues, and it appears to be a style conflict between our widget and your CMS. The dev team fixed it up for you using this CSS code:
input {
height: auto !important;
}
Please check if everything’s fixed now and let me know 
Widget does not validate Email and Phone entries
I wanted to let you know that right now our AI Chatbot app doesn’t support email or phone number validation. However, I added a feature request on your behalf for this important functionality: Add email and phone number validation.
Please feel free to add any further clarifications to the topic and upvote it to stay updated 
Form submits successfully when only Phone field is filled in
I absolutely get why this functionality is important for your case! While a feature request for it is still gathering votes, I’ll see if we can customise the form for you with the help of our developers. Please bear with me for some time, and I’ll get back to you with the news soon.
Drop a vote for the Wishlist topic in the meantime 
Stay tuned, and feel free to ask any questions you have further!
