The Near Me widget in ExperienceBuilder seems to have a bug where statistics calculated using the 'Add Summary' option are not affected by the intersect with a user-defined area. I have noticed this after the ArcGIS Online update last night.
For example, this:

Results in this output:

where the expression SUM({Shape__Area}) shows the sum for the full dataset, rather than the intersected area.
The expected behaviour is that SUM({Shape__Area}) would be equal to the Sum of the intersected area.
We use the 'Add Summary' option to get summary information from point datasets where 'Sum of the intersected area' is not an option, and from polygon datasets where summary info besides area is required. This will have a significant impact on the usability of some of our tools that rely on Near Me.
