Hello burn03,
Great job trying those steps already! Next, be sure to create a backup of your data: How to back up your iPhone, iPad, and iPod touch
From here, you can try resetting some of your iPhone's settings as described here under the: "Reset All Settings" section: Return iPhone settings to their defaults
Reset All Settings: All settings—including network settings, the keyboard dictionary, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
For context, this won't affect any of your personal data at all. However, this can often help resolve unexpected behavior when it comes to issues with settings not working as intended such as what you've described.
If it works, you can set up your settings the way you had them before. If not, feel free to just restore from your prior backup: Restore your iPhone, iPad, or iPod touch from a backup
From there your best bet would be to contact Apple Support directly: Apple - Get Support
We wish you the best of luck!
Take care.
