That is what I am trying to do but have not been able to get it to work.
As I am illiterate when it comes to php and I am just helping out our small (25 members) church we can’t afford to pay $25.00 for a plugin to alter the footer on a free (GPL) theme so I will have to continue to do it manually if and when there is an update.
I don’t understand why the footer details are called in via a hooks file instead of a footer file like most other themes are which can easily be altered and placed in the child theme directory and therefore not be overwritten when there is an update to the parent.
