I am working on mashup, where through nav bar I can switch between objects. The issue I am facing is when I drag an object onto the qlik placeholder, the qliksense object is not rendering and on preview it just shows delete icon. Also at one place I have embedded a google sheet, but that too is not loading properly, it just shows the google sheet name and a black window. Kindly help here.
Blank placeholder after dragging Qlik Sense object:
