deleting/editing contacts
I've looked in search but can't quite find the answer. I'm trying to edit a contact and the old info keeps populating in the contact and the new info is not saved. I've tried to delete the contact to start new and i get the following message: 'Not all contacts were deleted. One or more of the contacts may be read only'
How can I edit the contact or for that matter, delete the contact?
I have an iPhone 12 Pro
I do not have my contacts backed up to iCloud
