Audio track timing from Animate doesn't match in After Effect/Premiere

Hi,

Here is my problem: I animate a scene in Animate (with an audiotrack). I animate on the audiotrack, so the timing is right. I export my animation (without audio), put in in After effect to do some compositing and import the audio track I used in Animate to work with it in After effect. The exact same audio track. And, surprise, the timing is completely different. My animation who was perfectly fitting my audio track in Animate is suddenly shorter and the timing isn't the same. I checked the fps from Animate and After effect, it's the same. Same problem when I import my audio in Premiere.

What should I do?

Thanks and best,

E.
