The 30th season of Dancing With the Stars premiered on ABC on Sept. 20, 2021, at 8 p.m. EST. Many without cable have relied on streaming services like Hulu to keep up with the series, as it typically airs the new episodes within the first 24 hours after they premiere.
If you don't see the new episode on Hulu, it's possible it just hasn't been added yet. There is typically a delay between when it airs and when it's added to Hulu to stream, so you might just have to be patient.
The new episodes are only available for seven days on the streaming service, so be sure to keep up to date with the show. If you wait longer than seven days to stream it on Hulu, it will no longer be available and you won't be able to go back and watch it.
If there isn't a new episode available, check to make sure one aired the previous night, as it's possible there was a break in the season. If you still don't have the episode, ensure you're connected to the internet and try restarting the app.
