I'm using Resilio Sync Home Pro in Windows 11. I'm encountering a problem with partial downloads (with selective sync): when I right-click on a .rsls file whose icon shows that a download is in progress and select "Cancel receiving," nothing changes. I can remove from the device files that have fully downloaded, but can't stop downloads in progress, and I have a number of files that never seem to finish. Perhaps relatedly, there are quite a few very large !SYNC files in the .sync folder (all have names that a GUIDs).
