I have the same issues as many people are reporting here. It's been broken since Aug 2020.
- Roku Ultra, just upgraded from Roku stick because I thought that would fix it. NOT.
- Hulu enhance DVR subscription.
- Have restarted, removed/re-added Hulu App as suggested on many sites.
- For all live channels - Cannot Pause, forward, rewind, skip commercials, or start over. Even on the ones we're recording.
- For recordings, it's intermittent as to which features (pause, rewind, fast forward, etc.) work and do not work.
Basically, NOTHING about the Hulu subscription works. I've complained to support twice via online chat. Nice apologies and acknowledgement that there are issues, but no resolution and it's been 4 months.
