Start by reproducing the POST call that returns 408 and inspect GraphAuthClient.SendHttpRequestAsync, GraphHttpClient.SendAsync, and CommunicationsClientExtensions.cs:156. Done would require a confirmed cause for the missing GraphHttpClient.LogResponse method and a verified resolution of the call failure.
