No contacts available to share ETA

We appreciate the efforts!

Next, check to make sure all of your contacts are visible in the Contacts app, and not just a specific contacts group. To check for this, open the Contacts app on your iPhone, or go to Phone > Contacts, and tap the "Groups" tab in the upper left corner. From here, ensure that All contacts are selected.

If they are and you're still not seeing them to share your ETA, please get in touch with Apple Support directly. You can do that here: Get Support.

Have a wonderful day.

Hi there bbear08,

The steps on the following page often provide a solution when an app isn't functioning as expected.

If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open

We recommend trying the steps that apply to both the Maps and Contacts apps, and testing to see whether there's any change.

We hope this helps!

Greetings bbear08,

For help sharing your ETA while following a route in Maps, review the guidance found here, under the heading titled, "Share your estimated time of arrival (ETA)":
