Thanks for the question. Let’s see if we can isolate the issue further. To do so, try restarting/resetting your device:
If the issue persists after a restart, let's try a reset of your settings as outlined below:
Reset iPhone settings. Go to Settings > General > Reset, then choose an option:
Reset All Settings: All your preferences and settings are reset.
And finally, if the issue persists you can try a back up and restore as new:
After erasing and setting up as a new device, your device is now in a factory configuration. Test to determine if erasing and setting up as a new device resolved the issue. Content on the device may have caused unexpected behavior.
If the issue is still present, you may want to contact Apple Support.
