Connecting Smart Plug

Hi
I have bought a smart plug and followed instructions to set up in app on iPhone but if won’t let me progress to the ‘next step’ after the two lots of 5 seconds etc. I have checked in my Virgin Hub and tried disabling the 5 GHz setting and restarting the router. It still won’t work. I must be on my home wifi as that picks up data from inverter/battery ok.
Any suggestions?
Thanks
Kate

The app needs location permission to get your Wi-Fi name.

Wb1 I bet iPhone.

When the permission comes up, default is to ignore them.
Network scan, is one permission needed
