Why is security and overall check showing as grey "unknown" (overall status=2)?

By default, if either Photo Embedding Type check from authParams or Electronic Device check from livenessParams are enabled but not performed due to some limitations, it's marked as WasNotDone. Such limitations include:
 
1. Resolution is too low to perform Photo Embedding Type check.

2. The processed image contains an already cropped document with no background, so the Electronic Device liveness check cannot be performed.

In all such cases, the overall security checks' status will also show up as not performed.

To override this behavior, use the strictSecurityChecks parameter. When enabled, this parameter marks security checks that don’t meet minimum requirements as Failed (instead of WasNotDone), which causes the overall security status to be failed.
