I need to add a 5th data source to a dashboard that already has 4 data sources. Easy enough to walk through the steps but when the dashboard displays, no data (old or new sources appears) and the icon just keeps spinning. Ideas? Thanks!

That sounds like something may not be working as intended. I'd suggest contacting support to see if they can help.

Adding a new data source to an existing dashboard? (Old data "disappears" and the icon just spins!)
