Trigger stops working after publishing + States not working on mobile

Thanks for sharing your file with me, Kamille! It sounds like you're seeing two different issues here, so let's tackle them one by one.

1. 'Jump to slide' triggers aren't working correctly. 
   Were you viewing the published output locally when you noticed this happening? Instead, try hosting the published output on a web server or a learning management system to ensure all of the features in your project work properly
   
   I published your project for Web and hosted it on Tempshare. Here's a screen recording of my testing. I did find that the course took a little while to load at first, because it has so many media files in it. You can also test the link to your published course here!
2. Hover states aren't working on mobile devices.
   There actually isn't a hover state on mobile devices. Instead, you'll want to use a selected or visited state. 

I hope that helps to clear things up. Let me know if you have other questions!
