Hi, thanks for the reply.
This is a hosted blazor WASM app. To run it you need to set the startup project to Damselfly.Web.Server. The app takes a single command-line parameter - a folder that contains images which the app will index.
To repro the problem, drop any image with GeoData into the folder specified on the command-line, and then when the app starts up, double-click on that image in the browser. You should then see the image with some details panes on the left-hand side, one of which is a 'Map view'. This should display a map, centred on the geolocation of the picture, but no map ever renders. See screenshot - I've indicated with the orange circle where the map should appear.
Any clues would be great
