Android Kotlin: D/AdobeExperienceSDK: Edge - EdgeExtension - Identity shared state is pending, could not process queued events at this time, waiting...

Trying to send event to AEP from Android Kotlin. While request went initially, now we are seeing  Identity shared state is pending and message is not reaching AEP. Want to know what could be the issue.

Steps Followed:

Initially Registered following

Edge.registerExtension();
Identity.registerExtension()
Messaging.registerExtension(); // register Messaging

MobileCore.start{
    MobileCore.configureWithAppID(ADOBE_LAUNCH_CLIENT_ID)
}

At point where we want to send Event

val xdmData:HashMap<String, Any> = HashMap<String, Any>()

Identity.getExperienceCloudId {
   ecid = it  // ECID is got successfully
}

xdmData.put(tenantId, reviewXdmData);
val experienceEvent = ExperienceEvent.Builder()
    .setXdmSchema(xdmData)
    .build()
Edge.sendEvent(experienceEvent, null)

Please suggest what we are missing and how to resolve the issue
