I have hooked up a Ring Floodlight Cam but I am not able to get into setup. I scan the barcode and downloaded the Ring App and the furthest I can get is to get the light at the bottom to start blinking. When I go into setup on my iPhone 6Plus nothing happens. Is this because the IoS is 12.4 and I need a newer IoS? 12 is the most recent IoS that will run on this iPhone.
