I went on Tubi this week and found out that The Flintstones is no longer on the app. I also discovered that in a search, The Flintstones got moved to Hulu. It seemed that the modern stone age family didn't have a long run on Tubi.

The Flintstones is now back on Tubi.

Yabba dabba doo! I saw The Flintstone back on the Tubi app.
