Hey Rhapsody07,
In addition to the guidance offered in the previous reply, we also want to recommend that you try rebooting your iPhone and testing the issue again. Then if it continues to occur, double check that you have the latest version of iOS available and if you're able to update, do so and see if that helps.
Here are the steps for those processes:
If those steps don't resolve the issue, you might want to reach out to Apple Support directly. If support is available in your region, this will let you work directly with an AppleCare Advisor who specializes in resolving this exact type of issue. You can begin by reaching out here: Get Support
We hope this does the trick for you!
Cheers.
