I've noticed that the select tool is pretty buggy in Experience Builder, when selecting a large number of features. I've embedded a video that shows how it doesn't select all features, when zoomed out and selecting a large number, but works fine when zoomed in.
Is anyone else seeing this?
I've certainly seen behavior like this. I believe there is a limit to the number of features that can be selected. Can you confirm how many points are being selected in the video above? You could add a text widget that shows the COUNT() of the selected features to make it easier.
A previous solution, is to increase the data source page size (by default 100) to a large number;
After the latest AGOL 2023 Oct release, the issue has been resolved so it shouldn't cause any cap issue. Thanks.
