I had a very similar issue after installing WatchOS 7.3.2. No matter what I tried I couldn't get the Watch symbols to download. I even raised a TSI. While I was waiting for a response from Apple I tried opening another project and noticed that the symbols were being downloaded successfully. Then when I subsequently opened the project experiencing the issue I found that the symbols were now successfully downloaded! So, if you experience this issue it might be worth checking if it only affects one of your projects.
