The course player is a browser-based app, so often when we have problems with it this has to do with your browser. This can be really frustrating, but trying a few different things can help - you can also contact your coordinator if you find the following instructions confusing. Firstly, make sure that your browser is up to date. The system supports Chrome, Firefox, Safari and Microsoft Edge, but you need to have the newest version installed for it to work properly. If that has not helped, refresh your cache and restart your browser. This is often all you need to resolve basic issues! But if it still does not work, try accessing your site in a Private or Incognito window, like Chrome's Incognito Mode, or Firefox's Private Window. This opens a fresh browser window without any extensions or settings blocking your content. If none of that has helped, we recommend you try out a different browser (Chrome, Firefox, etc) - sometimes the issue can be browser specific. If you have one available, you can also try a different device or computer (mobile phone, tablet, PC/Mac laptop/desktop, etc.). It is rare, but sometimes a certain device has trouble with a content type. Restarting your device might also do the trick. Please make sure to let your coordinator know if you are having persisting problems and trouble accessing the content!
