And since news advised it and I happened to have my secondary computer on, still having the same thread expansion issue on one computer only that only turning the beta off seems to resolve. Basically the one where it sits there loading forever and doesn't expand the thread.

And honestly, using the beta bogs down thread expansion a lot even on the computer it does work on, often temporarily freezing my browser with a long thread for a minute or more and that is not in the least bit tolerable when the current one works almost instantly.
