With iOS 12, Siri began offering shortcut suggestions and more via the lock screen. You can disable these suggestions for individual apps or disable all Siri suggestions completely to clean up the lock screen.
Siri Suggestions is a little known feature that lets Siri look at the tasks you perform regularly and then offer a shortcut to those tasks at the best time. A good example of this would be if you ordered a coffee in a certain time or place. Siri would theoretically notice this and then start recommending that action when the time is right. All you have to do is click on the message to perform the action.
Depending on the app in question, it might be something you are looking for, if Siri makes suggestions that appear on the lock screen, but if it starts to get a little too chatty, or starts submitting unsolicited apps, you may want to turn it off. Thank you very much, you can disable the specific apps feature, rather than this being a complete or nothing business.
