Since the Enter key on Android changes to a Next key when you type inside a form field, there is no way for me to hit actual Enter which the input field for adding a new guest to an invite seems to listen to. Please handle the Next event for that particular field, or add support for , or ; typing after the email to add the email to the list of guests. I clicked on Update multiple times before, not realizing that the email of the guest I wanted to add was only in the input field but not actually added to the list of guests. Automatically adding it onSubmit would be much better UX as well.
