I am having a similar problem.  I've taken the truck to the dealership 3 times to update the onstar module and all software updates.  Everything seems correct at the vehicle level.  I have uninstalled and reinstalled the app multiple times now and it still reverts back to Nov '23.  What do I need to do?
