iPhone 8 plus not saving contacts
I tried to enter a new contact, phone contact. etc. on my iPhone 8 plus.
The iPhone 8 plus will not save it.
I entered the same contact into my contacts on our iMac desktop and it saved there but did not transfer to my iPhone 8 plus.
How can I fix this issue and enter new contacts into my iPhone 8 plus?
Thank you in advance.
iPhone 6s Plus, Other OS
