From time to time contacts need updating, if someone gets a new phone for example. If you find the contact that needs to be updated, you can click into the contact and their page will load.
In the grey box where you’ll find their contact details, to the right is the edit button. This loads up a page the same as creating a contact page. You can make any amendments that you need to.
Before leaving the page remember to press save at the bottom of the page to get your changes saved.
