Changing picoreplayer wifi

Hi,

Setup picoreplayer v8 on pi Zero 2 W and all working great on my wifi. Given to friend as a gift but their iPeng not showing the player.

I had edified the config file to suit their wifi but iPeng not showing the player.

I’ll pop round to take a closer look but presumed the pi takes this file settings each time or does it only on first config? Should I be editing somewhere else?

Thanks
