Changing the social media information that is linked to a contact can be done as follows:
In the contact details screen, under ‘Social Feeds’ press on one of the social media network icons then search for the correct social media profile and match.
Alternatively, in the contact details screen, press the contact’s photo and hold for several seconds. This will take you to a window where you can confirm the information or dismiss it. Clicking on dismiss will take you to the social network search screen where you can search for the contact’s correct profile.
