Downloaded iOS 11 on a few iPads to see how it worked, and Self Service will not download. Asks for sign in to iTunes. Anyone else getting the same issue and know a workaround?

Downloading Self Service on iOS 11

+14@avargas From my understanding you need to update your JSS to the most recent version. The older version broke device based app assignment.
There is another discussion here:

@avargas You have to go to your JSS and modify the self service setting. Go to global management > Mobile Device Management > Self Service and change the install automatically setting to 'Neither (manual installation)'. Then in your app settings for self service input the following information under the app configuration tab:
<dict>
<key>INVITATION_STRING</key>
<string>$MOBILEDEVICEAPPINVITE</string>
<key>JSS_ID</key>
<string>$JSSID</string>
<key>SERIAL_NUMBER</key>
<string>$SERIALNUMBER</string>
<key>DEVICE_NAME</key>
<string>$DEVICENAME</string>
<key>MAC_ADDRESS</key>
<string>$MACADDRESS</string>
<key>UDID</key>
<string>$UDID</string>
<key>JSS_URL</key>
<string>https://mycompany.com:8443/</string>
</dict>
Also make sure you enable 'ASsign VPP content' for the self service app to ensure its purchased via your VPP program
