I recently bought a Canon EOS Rebel T6i for my wife. It has built-in WiFi so we can connect with our smartphones. I was able to successfully connect my iPhone (both using a Camera Access Point and in Infrastructure mode) and it worked fine. However, when I disconnect my phone and try to connect my wife's iPhone it doesn't work. She is able to log in to the Camera Access Point wifi signal, but then when she opens the Canon Connect app it is not able to make the connection to see that there is a camera to connect to (even though it is on the Camera's wifi network).
Any tips on what might be causing this? When I erased the settings and set up my wife's phone first I was then unable to connect my phone. Is there a single phone limit on each of the connection profiles? I looked and haven't been able to find anything on that.
