Spreadsheet tool in v8.5 - does it work?

Trying to confirm if the spreadsheet tool in v8.5 is working for anyone in the following manner...

Created dashboard with the spreadsheet tool.  The page renders fine...

However, when doing something as simple as Save As, the following message is generated.

Excel file is defined in the configuration.  One client mentioned this, so I tested this on another client with the same results.

Heard this is fixed in v9.0.  Is this correct or am I missing something?

Thanks for any input!
