Vimeo autoplay not working on mobile

I have a little problem with a vimeo video that not working with autoplay on mobile device. Any idea ?

<div class="video-cover">
  <video width="100%" autoplay loop playsinline data-object-fit="cover" data-autoplay="true">
    <source src="" type="video/mp4">
    Your browser doesn't support HTML5 video tag.

video {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;

.video-cover video {
  object-fit: cover;

I have no feedback from vimeo, maybe is the subdomain that block movie ? Because the movie play when i’am in webflow editor
