I only just now became aware of the "Apps with usage access" preference view. However I'm irritated.
The permission was deemed important enough as to warrant a separate setting view to provide control and summary to the user, while at the same time there is almost no explanation as to what it does. On my OnePlus, there is not even a help page and even the internet gives only a pretty vague "Allows access to usage data" as an explanation
So, exactly what kind of access does an app get if it requests (and receives) usage data access? And if usage data I would really like to know what kind of usage data.
Android version is 8.1, should that make a difference.
