We have many players using the same machine, each using the app on their personal phone (with their personal customization). Does the machine sync to each player's app when it connects? When a player doesn't use an app, does the machine default to the last player's customization or will it use the pre-programmed drills?
This machine is really very convenient for training and is necessary if a person is engaged at more than an amateur level to achieve the best results in training. If you can not figure out its settings, I would recommend you to seek advice from the sporting goods store dunham sports , as I am sure that you can be helped with your problem.
