ArcGIS Online Summarize Within - length units only

Question

In going through the Solve a Spatial Problem tutorial, when attempting to run the Summarize Within analysis tool, the Calculate statistics section allows only for Summarized length units, not Summarized area units. Specifying a linear unit causes the tool to fail.

Thanks @CJ_Panorama and @Chris_Sutton_WIU for reporting this issue.
We think we've been able to figure out what's going wrong and will fix it in the next update to ArcGIS Online. In the meantime, the issue can be resolved by ensuring that a unit system is selected either for your current user or for your organization as a whole.

If you have the default administrator role or a custom role with the appropriate administrative privileges, you can set the units for their organization by going to Organization > Settings > Map > Map Defaults > Units.
Then switch to Metric, or switch to Metric and then back to US Standard, depending on your preference. You should see a notice at the bottom of the screen that the Units have been updated successfully.

If you don't have an administrator role, you can configure the unit settings for just your user. Once you are signed in, click your name in the banner at the top of the site, and click My settings. On the General tab, scroll down to units and select either US Standard or Metric, depending on your preference. You should see a notice at the bottom of the screen that the Units have been updated successfully.

Please give either of these a try and let me know if it doesn't resolve the issue.
Sorry for the inconvenience, and thank you again for letting us know about it!

Cheers,

This is still a problem. I'm trying to summarize a polygon dataset using the Summarize Within widget. With the polygons set as the input features, the "Calculate Statistics" panel has a required parameter of "summarized length units". I would think it should say area units instead. The tool then gives an error "The shape units Miles are not valid when summarizing a Polygon layer".

That is quite odd. I recommend you contact Esri Support, who will be able to hop on a screenshare with you and hopefully better troubleshoot what is going on.
