There's not much substance in this post. Can you please expand a bit, make it clearer what the expected experience should be? I.e. is this going to replace the cmdlets, or is intended only as a replacement for the web service (bulk data retrieval). There is no payload or $filter support, so it seems to be the latter, but a clarification might be nice.
Also, are there additional steps required to provision this or is the rollout incomplete, or did you miss the memo on service principal-less auth:
"message": "Service principal-less Authentication failed: the service principal for App ID 8bd644d1-64a1-4d4b-ae52-2e0cbf64e373 was not found. Please create a service principal for this app in your tenant. Provisioning may take several hours to complete.

Hi VasilMichev​ , Thanks for your feedback. Message Trace support on Graph API will be replacing Message Trace support on Reporting Webservice which customers are using for bulk data retrieval. This will not replace the Message Trace V2 cmdlets. We've added more context for the service principal-less authentication error in the blog under Onboarding for the meantime and we will be sharing a detailed onboarding document soon.

Indeed, we are aware of this (service principal requirement), and the team is working on it.
