Are there any characters that iOS 10 doesn't like for wifi passwords? I'm asking because it seems that iOS doesn't like our strong passwords (12 characters long with upper and lower case letters and special characters). These same exact passwords work great on our windows pcs and Xbox as well as our Apple TV. On our iOS devices, we'll get the 'password incorrect' error and the device won't connect. We've performed all the usual troubleshooting- verify the password, forget and readd the network, reboot device, reset network settings, etc - all to no avail. Please help.
