Missing data in the Email app usage report

Hi @Anne Michels,

I just talked to Support. Here are what I get:

1. Why neither email app usage report in admin portal nor PowerShell get-connectionClientTypeDetailReport does not show my mailbox's OWA usage? Support: That's probably due to my browser Chrome and I am suggested using IE.

2. Why PowerShell get-connectionClientTypeDetailReport returns more users' OWA usage than email app usage report in admin portal? Support: Usage report may have its own logic to filter out some data. Belive in PowerShell if they are different. 

However, that's not convincing me. It seems I cannot get a comprehensive answer from Support. If usage report and report PowerShell results have limitations (it would be great if you can confirm this with your dev team), I would suggest Microsoft write down in documentation and enhance in future.

Thanks,
