Not sure what Workspace One version each of you are using but on version 1811 inside the Launcher Config Profile you have an option to lock down settings more granular than just default config. After setting that my devices are only able to access the settings I allow per the granular restriction set inside the Launcher profile. Also launcher version installed is 4.1 on Android running 8.1.
Hey, I was with this same problem here. Running Android 7 and 8, single or multi app, and with the 4.3 Launcher version I was not able to see the status bar, use home or app manager physical buttons, edit wifi and bluetooth settings. So I did a rollback to 3.3 Launcher version and then all of those problems disappeared. I hope that this tip helps you and other people with these same troubles.
