Try a restart of the iPad and iPhone. Not sure what iPhone you have, but if it has a home button you can do this by pressing and holding both the home button and the power button till you see the Apple Logo on the screen, If you don’t have a home button, then follow these steps:
- Quickly press and release the Volume Up button
- Quickly press and release the Volume Down button
- Press and hold the Siri/Lock button till you see the Apple Logo on the screen
If you see a slider “Slide to turn power off” ignore this message and continue to hold the Siri/Lock button until you see the screen turn off and the Apple Logo appear on the screen. Once you see the Apple Logo you can release the button and allow the device to turn back on and finish loading.
Do this to both the iPad and the iPhone (same steps for both) and then try again. It could just be something in the software is stuck and this restart may get it working properly.
