I was watching the rings of power and it started with a "Commercial free experience provided by so and so" with a long ad at the start of the episode, and then a third of the way into the episode, at a critical action part, it broke in the middle of the actor's sentence to a 6 minute ad block.

I exited playback and haven't gone back to finish it. I'll wait for it eventually to make it to a Blu-ray release someday.
