I can't seem to get Paramount plus shows to work through my iPad in Apple Air play through Apple TV to my Samsung TV screen?

Hello, try to follow these steps in this article. If screen mirroring or streaming isn't working on your AirPlay-compatible device - Apple Support

Do you have the Apple TV box? If so, which model?

I don’t think that any 2014 TV supports AirPlay directly. You may want to connect an external streaming device that supports AirPlay (and/or different apps).

That can be an Apple TV box or Roku for AirPlay. Older models may not support AirPlay from the streaming service of your choice. Apple TV (4th generation or later) recommended.

That can be an Apple TV box, or Roku, or Fire TV, or Nvidia Shield, or Chromecast dongle for streaming device apps. For select apps, more devices may be supported. For the Apple TV box, again 4th generation or later recommended.

On which devices can I watch Paramount+? - Paramount+ Support

Disney+ supported devices - Disney+ Help Center

Hulu supported devices - Hulu Help Center

Also note the difference between Paramount+ in the Paramount+ app, and Paramount+ in the Apple TV app. These have different requirements and are not exchangeable on the same subscription … mostly.
