Sprout Forms: empty phone field still shows error "Phone is invalid. Example format: (506) 234-5678" Running Craft CMS 3.3.20 and Sprout Forms Pro 3.6.8


form has Phone field
submit form with no value in Phone field
form reloads with error message "Phone is invalid. Example format: (506) 234-5678"


If valid phone number entered form submits fine.
This was a bug and is resolved in release Sprout Forms v3.6.9 and Sprout Fields v3.5.2.

  This is a bug in Sprout Forms v3.6.8. We'll have a fix out for this shortly and I'll update this comment when we do.
