CONTACTS SUGGESTIONS IN PHOTO SHARING

Hi MaraAkin,

Thanks for posting to the Apple support communities. I understand that you would rather not see suggestions for sharing in the Photos app. I’m happy to help out with this.

 This could be related to your settings for Siri suggestions. “To turn off Siri Suggestions, go to Settings  > Siri & Search, then turn off any of the following:

-Suggestions in Search

-Suggestions in Lookup

-Suggestions on Lock Screen

For a specific app, tap the app, then turn off Show Siri Suggestions.”

In this case, you want to apply those above steps to the Photos app. About Siri Suggestions on iPhone

Have an awesome rest of your day!
