'This content isn't available' using Power BI Embedded in Wordpress

[ds-elevate]

Using the Power BI Embedded for Wordpress plugin, (similar to the issue described here), we're getting ''This content isn't available.' rather than the embedded reports expected. 

I'm using Firefox and when I open a private window, the reports show properly just as they did in my default window before this error showed up.  Other users with Chrome have the same problem. 

In the now-abandoned-seeming plugin support forum, they seemed to think it was a token issue and ultimately solved by MS. 
Any ideas on how to fix (or where to log an issue if this is the wrong place)?

Have you already assigned capacity to the workspace you're working out of?

Yes. 

It appears to be solved after wiping site data for the site the report was embedded in. 

This implies some kind of bad data was cached locally that prevented the reports from reloading properly for days/weeks.
