Text messages on 2015 Chevy Equinox MyLink

Until about 2 or 3 years ago, I used to be able to get text messages on the MyLink screen on my 2015 Chevy Equinox, when my iPhone was connected via BlueTooth. In BlueTooth, I have the option to enable notifications turned on. About 2 or 3 years ago, this stopped working. At the time, I was using an iPhone SE, and thought maybe it had something to do with the phone. But now I have the same problem with a brand new iPhone 16. Did an iOS update a few years ago break this feature, with no way to fix it? Or am I doing something wrong? Thank you.
