I am able to connect my mobile (Samsung S6 Edge) to the camera (Nikon D5600) via Bluetooth in the Snapbridge app.
PROBLEM: When I press the "Remote Photography" or "Download Photos" button, the Snapbridge app successfully starts the camera's wifi but keep trying to connect it for an indefinite time. I have already disconnected my home WiFi (basically my mobile is not connected to any Wifi). If I go the Wifi setting of my mobile, I can see that my Mobile is connected to the Camera's wifi but the Snapbridge app does not recognize that connection and hence I am not able to use "Remote Photography".
The Snapbridge app keeps trying to connect to the Camera's wifi as shown in the screenshot (but if I check my mobile's wifi setting, I see that the mobile is already connected to the Camera's WiFi).
