Activity Zone editing is broken

I have a big issue with the way you draw “Activity Zones” in the Eufy app.
Selection handles close to the edge of the screen simply can’t be dragged. In some cases other iOS edge-dragging interface modes engage instead. In other cases, selection handles that are clearly in from the edge of the screen can’t be dragged.
I conclude that this functionality is broken and a source of considerable frustration.
Eufy, fix this!

Is it better on android?
