Research direction
Investigate the image loading mechanism for thumbnails in the subscriptions section (likely in the feed adapter or view model). Check the repository's usage of image loading libraries like Coil or Glide. Look at the subscription feed fragment and related data fetching code for potential race conditions or caching issues. The issue mentions thumbnails not loading until the video is played, so examine the transition between thumbnail loading and video playback.
