Hi there rivercitytunester,
First, you can see if restarting your iPhone 11 may help. Restarting can refresh the iOS and may help resolve unexpected issues. The steps below show how, if needed:
"How to restart your iPhone X, 11, 12, 13, or later
- Press and hold either volume button and the side button until the power-off slider appears.
- Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
- To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."
Those steps, and more, can be found here: Restart your iPhone - Apple Support
Another step you can take is to ensure that your iPhone 11 is fully up-to-date. Updating to the latest iOS can resolve any issues that might be present in the previous iOS. The step below show how to check and update if there is a software update available:
"Update your iPhone or iPad wirelessly
- Back up your device using iCloud or your computer.
- Plug your device into power and connect to the internet with Wi-Fi.
- Go to Settings > General, then tap Software Update.
- If you see more than one software update option available, choose the one that you want to install.
- Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do."
