According to this document:
https://documentation.meraki.com/SM/Device_Enrollment/Enrolling_Devices
If an iOS device is connected to a Meraki wifi network it should be able to enroll without knowing the network ID code or the qr code, etc. I have a full Meraki stack, MS, MR, MX, and when I run the SM app on iOS 12.2 (iphone and ipad), it doesn't detect any Meraki networks. I still have to either scan the qr code, or, punch in the network ID code. Is there something specific I need to configure for this to work? I've been searching for a long while and can't find anything.
