Re: Failed to refresh access token. { "error" : "invalid_client" } on perfectly good client
+1. We're seeing a huge number of these errors - on about 2% of our calls.
Retrying seems to help. We moved to the latest .NET release recently.

Re: ReportUtilities.DownloadClientReport throws System.NullReferenceException
We encounter this too. Added retry logic and that seems to have fixed it. Its bad though to have to catch a NullRef and retry on that.
