I've installed Mobile Console Kit by passing the git repository into the Package Manager. Immediately after this a lot of errors appeared in the Console:
Library\PackageCache\[email protected]\Editor\EditorCore\LogEditor.cs(41,83): error CS0117: 'Log' does not contain a definition for 'k_ProBuilderLogFileName'
Library\PackageCache\[email protected]\Editor\EditorCore\LogEditor.cs(27,25): error CS0117: 'Log' does not contain a definition for 'SetLogLevel'
Library\PackageCache\[email protected]\Editor\EditorCore\LogEditor.cs(28,25): error CS0117: 'Log' does not contain a definition for 'SetOutput'
and so on. It looks like the Log.DLL causes this problem by hiding the Log class.
