I am using MobileFirst Version 7.1.0.00.20161118-2214. In this fixpack version my apps started pushing client logs as UNKNOWN in both android and iOS. Not sure whats the issue.
"appName": "UNKNOWN", "appVersion": "UNKNOWN", "deviceId": "UNKNOWN", "model": "UNKNOWN", "systemName": "UNKNOWN", "systemVersion": "UNKNOWN"
Sounds like a regression in the latest iFix release. You know the drill - will require a PMR to provide you with a fix.
Try restarting the server, though?
