Hm. So just for laughs, went back to my download queue; paused all; then restarted SF (and make that damn black friday banner go away already!!). Then hit the > arrow on episode 2. Downloaded up to 80/mbs, without any trouble (4K/DV,DA). Waited a little bit while working on something. Didn’t close SF. Then hit > on ep 3. Also no issue. Repeated on ep 4, all good.
So, guessing there might be some pre-caching, look ahead going on with having entire season running in queue (‘waiting to download’). In this case, doing “one at a time” works as expected, and relatively quick vs freezing at 20%.
