I try to visualise the map using the Map Viewer application. After adding the ‘Shadow’ effect (or any other effect) for the points, it is not possible to generate a map with a legend. When generating the map in the ‘Print’ panel and selecting ‘Include legend’ in the advanced options, the legend does not show up on the PDF printout (and any other printout regardless of the template and file format).
How do I change this?
I don't have a workaround for you but the issue has been logged and you can track it here: BUG-000166541
