cellular data app toggle switches
For clarification: my/our issue is with the cellular data app toggle switches. For example, when a user turns a switch "on" from an "off" position, the setting is not respected by the system. The switch will appear to change to "on", but if you try to use the affected app, it won't permit cellular data to go through. Then, if you go back and check the cellular data app switches in the Settings app, you can see that the switch has reverted back to its previous position, in this case "off".
