    Based on the logs you provided, and this part of the error message:
    System.MissingMethodException: Method 'Android.Support.CustomTabs.CustomTabsIntent.LaunchUrl
    looks like either Chrome is disabled or not installed on the device. MSAL can only launch the UI if Chrome or chrome custom tabs is installed on the device (and enabled). We know this is not an ideal scenario, and a future release of MSAL will provide options for the developer to work around this issue. The implementation details have not yet been decided. You can follow the discussion and provide input though...please see these issues one and two
