An analysis is performed on first and second product information to determine a relationship between a first product and a second product. In response to a first notification from a first backend system, a first message is transmitted to a mobile device of the user indicating that the change of a first activity is needed. It is determined whether a modification of a second activity is needed based on the relationship information of the first product and the second product and in response to determining that the modification of the second activity is needed, a second message is transmitted to the mobile device, indicating a possible modification of the second activity and offering a list of one or more options to modify the second activity. A live communications session is established between the user and a support agent of the server to discuss the possible modification of the second activity.
