My apologies if I am just doing something incorrectly, but I noticed that when I tried to use a SSID of: "User’s Wi-Fi Network" and generate the QR Code, it doesn't log me in like you would normally expect.

When I use my iPhone camera to scan the QR code, it pops up with the message "Join "Users Wi-Fi Network" Network". Note that the apostrophe in the original SSID is now missing, which I suspect could be why the log in is not successful.
