Hello CL247,
Welcome to the Apple Support Communities.
It looks like you're running into some issues with using Multitasking on your iPad. There are a few steps we can offer here in the Communities that may help to resolve the issue.
Power cycle the iPhone with these instructions: Restart your iPhone - Apple Support. While simple, this can refresh the iOS, apps and connections.
The latest version of iOS is 17.1. If you visit Settings > General > About, and this does not show for Version, you'll want to update the software on your device to see if this helps to correct the issue. Here's information on how: Update your iPhone or iPad - Apple Support.
If not, next open the App Store, and look to see if you have any app updates available. If so, please complete the app updates. How to manually update apps on your Apple device - Apple Support. Test to see if the issue remains.
If everything appears up-to-date and you still have the issue, you may want to reach out to Apple Support directly. You can reach out to them by clicking here: Get Support or over the phone by calling the number that is most local to your region: Contact Apple for support and service - Apple Support.
Best wishes!
