Announcement Bar Gradient Animation No Longer Working

Hello all. As of this week this animated gradient on my Announcement Bar has stopped working and I am not sure where to look for the issue. The animation is still working on the header text throughout the site, as well as the "in season" tags within my store, but not on the Announcement Bar. I have included the code for this below, but let me know if you need any more information. Thank you so much for your help.

// Color Animated Announcement Bar //

[data-header-theme] .sqs-announcement-bar-dropzone .sqs-announcement-bar {
  background: linear-gradient(99deg, #e6d1b8, #d8a674, #b7b8aa, #aab6bb);
  background-size: 400% 400%;
  -webkit-animation: AnimationName 6s ease infinite;
  -moz-animation: AnimationName 6s ease infinite;
  animation: AnimationName 6s ease infinite;
}
