Wifi not auto-connecting on Android

Question

Hi, 
 since a while our Samsung Galaxy Tab A 2016 are not connecting automatically to WPA2-PSK Wifi with Wifi profile deployed through Sophos Mobile (on-prem), but it is possible to connect to the deployed profile in the settings app. When creating the Wifi profile manually in the settings app auto-connection is working as expected. 
 We are experiencing the issue with the latest Sophos Mobile app version 9.0.3410, but also tried older versions 7 and 8. We have tested with both hidden and visible SSIDs. Sophos Mobile server is at 9.0.2 (latest), the tablets are running Android 8.1 (latest). 
 Does anyone has a solution for this? 
 Kind Regards, Martin Feuerstein

Problem solved or to be precise, a workaround: The WiFi profile was set to "WPA2 Personal" in the Sophos UTM - the tablet is not connecting automatically (but it is possible to connect manually). When the profile is set to "WPA/WPA2 Personal" or "WPA Personal", the tablet connects automatically. 
 
 So maybe the WiFi profile on the device created by Sophos Mobile contains wrong settings?
