Office 365 Sharepoint dashboard list data source with managed metadata term store fields

I am creating a time tracking list and dashboard in Office 365 and can't get it to work right.

Step 1 is working and complete: Create Timesheet Custom List

Custom content type with the following site columns:

Project (Managed Metadata from Term Store)
Month (calculated Value from Date)
Year (calculated Value from Date)

Step 2: Create Excel Dashboard

This is working but only in excel.

3 charts
Hours by month
Hours by resource
Hours by project

Resource (Created By column)
Project (Managed Metadata from Term Store)

-The excel file Dashboard created in excel 2013 using iqy file (export to excel) from timesheet custom list
-Published excel workbook to office 365 sharepoint site in site assets

Step 3: Using Excel Web Access Web Part to publish dashboard

Viewing Dashboard in SharePoint via web browser = Error: we were unable to refresh one or more data connections in this workbook. the following connections failed to refresh

Dashboard refreshes with excel on PC.

Some sites mention to use oauth connection to connect to list data but then the project field (consumed from term store) does not return proper value.

Am I spinning my wheels here or is there no way to create a dashboard that contains managed metadata?

Thanks in advance for any help on this.

Just to share the solution... You need to create a workflow around the item in SharePoint Designer that pulls the managed metadata field and then stores the result in a workflow variable. You then create a text column that you write the workflow variable back to as text. Used the text column in your view and then it can be used with slicers on the dashboard.
