Hi,
I need help regarding a couple of different things , related to the Display a web map tutorial-
1:
Can someone please verify if the tutorial for displaying a web map is appropriate?
Link: https://developers.arcgis.com/qt/maps-2d/tutorials/display-a-web-map/
I am following this tutorial for Qt C++.
In the section - Initialize the map using a web map
Step 2 of the tutorial instructs to remove the following line:
m_map(new Map(BasemapStyle::ArcGISTopographic, this))
However, if you expand the Display_a_map.cpp code snippet in the Step 3 of the tutorial, this line has not actually been removed.
2:
I have created my own web map with the Map Viewer application.
A screenshot from my account:

I am trying to display this web map using the tutorial.
The only thing I changed in the code of the tutorial was the item_id in Step 3 of the section - Initialize the map using a web map.
When I build and run the code, the window in which the map is displayed is empty. This can be seen in the screenshot below:

However, immediately after this if I check my account again, the View Count for this map has increased.

Can someone please help me out in debugging the issue? Please find a minimal example attached in the .zip file, although I am not sure if the map can be accessed without my API Key.
Cheers,
Ritvik
