Thumbnails disappearing

Thumbnails will disappear when scrolling through episodes.
How do I fix this?

Need more information.

  1. Which Tablo (legacy or 4th gen)?
  2. Which app (Roku, GoogleTv, AppleTv, mobile ,etc)?
  3. OTA or FAST channel?

Thanks!

Thanks! I don’t have an AppleTv, but plenty of others here do. Hopefully they can help
