I want my Photon to be able to operate on either of two WiFi networks. I set up the device on network WiFiA using the IOS app. Then I took it to WiFiB and used the IOS app again to set up the Photon. I thought this would add the 2nd network to the list of possible networks to connect to. But when I took the device back to WiFiA it did not connect to the cloud. The Green LED just kept fast blinking.
What is the best way to manually set up the Photon to communicate using either WiFi network.
