CodePudding user response:

firebaseFirestore.collection("Users")
                            .document("[email protected]")
                            .update("phone",897389121 );

This code mean you are operate a document that id is [email protected], But it is a field value in you screenshot not id, In this scenario you have to run query first, Then update those documents.
