We are aware of an issue where some users are unable to edit their lineups. We believe this issue is on desktop only. If possible, please use the NFL Fantasy App to make lineup changes, or enable Classic View in the Desktop site (bottom right hand corner) in order to make changes.
We are also aware that this is impacting League Commissioners attempting to edit lineups using the Edit Team Rosters tool. We expect this to be fixed shortly.
We apologize for the inconvenience.
