Someone (likely my son) changing my controls
My son seems to have managed to get xfinity on his phone so that he can change the control settings to give himself extra time, change his scheduled downtime etc. He insists that he does not have access (he used to, but deleted it). This morning someone changed the settings again. Is there some way to either see who changes the controls or to delete the controls and start over, to cut off whatever he seems to be able to access? thank you!
