I dont have a text tone since the latest update 13.1.3 how can I remedy this?

Greetings Elfrun,

Thanks for visiting the Apple Support Communities! I understand your messages don't have a text tone on your iPhone as expected.

The following guide will help you to ensure you have a text tone selected for your device: Use tones and ringtones with your iPhone, iPad, or iPod touch - Apple Support

After confirming the above steps, let's have you ensure your notifications are properly set for Messages: Use notifications on your iPhone, iPad, and iPod touch - Apple Support

Let me know how it goes from here.

Kind regards.
