@apmasmelar_UDFJC - thanks for bringing this up. I checked your MV and ExB settings, and all configurations should be fine. It appears that the problem may have something to do with the second Coordinates widget here:
![TonghuiMing_0-1678084694290.png TonghuiMing_0-1678084694290.png](https://community.esri.com/t5/image/serverpage/image-id/64393iB2AD41708118C596/image-size/medium?v=v2&px=400)
In this widget, the added special SR does not support the mouse-hover-to-obtain-coordinate action, which might cause the popup not to show up.
If you remove the second widget or add a new one with SR supporting mouse hover, e.g. 4326, it works fine:

We will take a look at this special case. Thanks for the sample app.
