Heya @CodeSharePaul what did you do to get this working? I have a dsahboard that I'm trying to load chart.js into and although it worked perfectly well in Umbraco v7, it just won't work in v11. I've tried loading in:

assetsService.load([
  "https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.9.4/Chart.bundle.min.js",    
  "https://cdnjs.cloudflare.com/ajax/libs/angular-chart.js/1.1.1/angular-chart.min.js"], $scope).then(function() { ... }

I've also tried placing the references directly in the markup and the original

app.requires.push('chart.js');

approach but nothing is working. Any ideas?
