Trial License Key not working?

I’m not sure what is going on, but I am consistently getting an error about my trial license key not being valid (it has 28 days left)

Error msg: “Sorry! You have not set a License Key. You can request a free trial key from http://www.scichart.com...”

Code (trial key partially snipped):

class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    // Set this code once in MainActivity or application startup
    SciChartSurface.setRuntimeLicenseKey("w2q0iyS8UeR2HKF...uqUbxqjprSIvXJPibCSl1g6ag==")

    // Get the scichartsurface
    val surface = findViewById<com.scichart.charting.visuals.SciChartSurface>(R.id.id_scichartsurface)
    // Initialize the SciChartBuilder
    SciChartBuilder.init(this)
    // Obtain the SciChartBuilder instance
    val sciChartBuilder = SciChartBuilder.instance()
    // Create a numeric X axis
    val xAxis: IAxis = sciChartBuilder.newNumericAxis()
        .withAxisTitle("X Axis Title")
        .withVisibleRange(-5.0, 15.0)
        .build()
    // Create a numeric Y axis
    val yAxis: IAxis = sciChartBuilder.newNumericAxis()
        .withAxisTitle("Y Axis Title").withVisibleRange(0.0, 100.0).build()
    // Create a TextAnnotation and specify the inscription and position for it
    val textAnnotation = sciChartBuilder.newTextAnnotation()
        .withX1(5.0)
        .withY1(55.0)
        .withText("Hello World!")
        .withHorizontalAnchorPoint(HorizontalAnchorPoint.Center)
        .withVerticalAnchorPoint(VerticalAnchorPoint.Center)
        .withFontStyle(20f, ColorUtil.White)
        .build()
    // Create interactivity modifiers
    val chartModifiers = sciChartBuilder.newModifierGroup()
        .withPinchZoomModifier().withReceiveHandledEvents(true).build()
        .withZoomPanModifier().withReceiveHandledEvents(true).build()
        .build()
    // Add the Y axis to the YAxes collection of the surface
    Collections.addAll(surface.yAxes, yAxis)
    // Add the X axis to the XAxes collection of the surface
    Collections.addAll(surface.xAxes, xAxis)
    // Add the annotation to the Annotations collection of the surface
    Collections.addAll(surface.annotations, textAnnotation)
    // Add the interactions to the ChartModifiers collection of the surface
    Collections.addAll(surface.chartModifiers, chartModifiers)
}

Any assistance appreciated. Thank you.
