I'm having the same issue, using this URL: https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_ts/master.m3u8 Looks like it is reported over here as well: https://developer.apple.com/forums/thread/727288?login=true&page=1#751592022

Has anyone put out a bug report yet? I forget how to do that.

Same here. Was working until I upgraded. Been playing the same videos for years.
