Hello, they don’t use tracker proxy. The requested file is configs.php. Both tracker.php (replaces matomo.php) and configs.php show cors-error, but normal tracking works. Heatmaps (configs.php) don’t work. And yes, I can send you a link but prefer private email for that. Also, the link to the site goes directly to ms login page. So I’m not sure if you can see anything from there. Thanks!
