Hi there LindaSaucedo,
You'll want to start by making sure your iPhone is updated to the latest software version, which is iOS 16.3.1. You can see the currently installed version in Settings > General > About > Software Version. If needed, learn more about how to update your iPhone here: Update your iPhone or iPad - Apple Support
Also, check to make sure that the Ring app is updated with the guidance here: How to manually update apps on your Apple device - Apple Support
Next, check the notification settings for the app to ensure they're set up the way you'd prefer. You can do so in Settings > Notifications. This link provides more information about how to change your notification settings: Change notification settings on iPhone - Apple Support
If your iPhone and the app are updated and you've double-checked that the notification settings are correct, you'll want to work with the app developer to see if there are any notification settings in the app itself that can be adjusted. Also, they're best-equipped to provide some guidance about notifications from their app. This link will help you get started: How to contact an app developer - Apple Support
Take care.
