Looping animation in Figma Slides stops after one round

Hi all, I created a looping animation component using smart animate that starts automatically after a delay of 1ms. It works just fine when I preview it in the Figma file.

However, when I paste the same component into Figma Slides, the animation stops after one round when it’s supposed to loop back to the beginning. I’m thinking this is a bug since it works in the regular Figma project, but won’t work in Figma Slides.

If you’ve run into this problem, how did you fix it?
