This is a sample project based upon https://stackoverflow.com/a/79398905/1271826.

The salient aspects are:

1. Do not update cell with progress by reloading the snapshot if you're going to be doing isHighlighted sorts of animations. Just have the cell update itself.

2. I have simplified the JSON, carouselData. I have also simplified the cell. But this is unrelated to the basic fix, namely stop reloading the cell.

3. FWIW, I have retired IndexPath based updating. I have also created a new Download object to keep track of the individual downloads.

4. Since OP was using Combine elsewhere, I used ObservableObject with @Published property to monitor the state changes.

Developed in Xcode 16.2 and Swift 5.
