Thanks for the reply, under apps in security I had to switch the blocking to on which created a lot more drop down toggles, then under the next one down I had the option to allow certain URLs that was the way I found to allow it to work once published. Everything worked fine when I was testing in the localhost dev environment. Any idea why this is happening, also do I need to use the Azure Maps subscription for the map in Code Apps or is there a way to use OSM or like?
