Plan Needed ??

The Bluetooth Hands Free Calling is working fine. The main issue is that when you look at the settings for the dashboard and you select Speed Limit Sign. It is checked as being "ON" but next to that is a message that states, "Plan Needed". I have a plan and I read in some research, that any plan of On Star will be sure to keep the Speed Limit Sign active. Everything else seems to be fine, and have reached out to On Star several times. I am being told that a specialist will call me. Just happened that yesterday (9/11/24) on a trip, it started showing again on the dash screen and HUD. But about an hour later on a return trip to home, it was gone. At first I thought is was fixed as it worked briefly, but now back to where it states, "Plan Needed".
