Have followed the setup of Enrolling and Supervising iOS Devices using Apple Configurator 2.5 or Later using Manual Enrollment - Enrollment & supervision without Apple Device Enrollment Program. However, every time I Prepare an IPhone 5s running 11.3.1 it fails to install the Meraki Remote Management - "The configuration for your iPhone could not be downloaded from XXXX. Invalid Profile". Using MacOS High Sierra 10.13.4, Apple Configurator 2 v2.7 with the device successfully set to Supervised and Organization (XXXX) applied. Completion of the iPhone Manual Setup to select a valid WiFi internet connection succeeds but applying the Meraki profile fails as above. User Authentication Settings are set to Disabled in MSM and Apple MDM certificate is valid. Am I missing something to successfully deploy using this enrollment method? Thanks
