Hi @W_Leger, thank you for reaching out to us on Xfinity Forum. We directed your message to the proper teams to investigate. Please try exiting and relaunching the app on your Samsung TV, or try unplugging and replugging the TV to resolve this issue.
@W_Leger could you please let us know your timezone? We would need the specific hour and minutes of the time and date setting shown on your TV to help our engineer troubleshoot. Thank you
