Please keep in mind that we don't support Safari. Using it might cause unexpected glitches or errors:
Safari blocks media with sound by default. You can change that by updating a simple parameter:
1. In your Safari browser window, on the top, click on Safari > Preferences
2. On the top menu, navigate to the tab Websites, and on the right-hand-side, select Auto-Play
3. Click on the drop-down menu next to 'When visiting other websites' and select the option 'Allow All Auto-Play'.
You should now be able to play and hear all the media available in the simulations.
Alternatively, you can use any other of our supported browsers.
Please do not hesitate to reach out to our Support Team if you have any questions or are in need of assistance.
