Somehow my application on my iPhone Xs could no longer perform "Quick Pairing". Once I click on it, the "Choose a Wifi" shows Wifi SSID as "Wi-Fi" (refer attachment) and I could not view my home network nor change this. I have successfully added 3 sonoff R3 Basic and not could not add new devices.
I've tested this on another iPad and it does not have problem detecting my wifi. And yes I am connected to my 2.4Ghz network.
I've also tried deleting the application and reinstalling but still the same issue.
Fantastic Ariel. This worked as an interim until they fix the app.
Thank you very much Ariel
