Screen mirroring not working
Screen mirroring between ipad and iphone is not working. The screen mirroring window has a wheel in upper right hand corner on both devises that just spins and never makes any sort of connection.

Thats not how it works. You can only mirror to a Mac, an Apple TV or a compatible Smart TV. You cannot mirror from one iOS device to another one.
Use AirPlay to stream video or mirror the screen of your iPhone or iPad - Apple Support
