Hi,
Having the same problem here. Both the Tel No. and Email fields have changed style since the upgrade to 3.4 today. Previously the Phone Number field was a Text field, but in 3.4 it uses the the form Tag "Tel" and both that and the Email field gets validated. If I change the field tag for a phone number input back to text, I recover the form's css styling for that field, but we lose any validation. I happy with that for the phone number, but not with email. So for the moment I'm stuck with an email field which visually doesn't fit with the rest of the form.
Any help would be appreciated.
Thanks,
Owen
