Animation not loading

Hi team,

I've created a gamified module with the use of Storyline 360.

Whenever I try to review this module on LMS, the animations are getting loaded properly.

On Internet Explorer, some of the animation and GIFs are not working.

On Firefox, a module is not opening, it's showing loading icon for the longer time.

Can you guys please help me with this issue, as I need to go live with this project at the end of this week?

Regards,
Amit
