@mdma Hi Mat, I am also experiencing the exact same issue. Installed latest firmware, factory reset many times… every time I set up the Photon with the iOS app i get through the entire process, but the app says the device is offline and the LED is breathing magenta… this is where I’m stuck. If I push a button or toggle power the LED goes to solid green. I’ve also tried safe mode. Here is a full memory log that you requested form @hmbucker above. Hope this helps.
