MyChevrolet App (IOS) - My Radio Favorites Connection Error

Don, I have a similar issue with our 2019 Equinox.  I recall getting the "Connection Error" a while back but my latest issue is I can't add more than 3 Favorites with my user account selected in the vehicle.  When I add the 4th, the "Audio/Favorites" quits working.  When I delete all the Favorites in the vehicle, it starts to work again. The Media > My Radio Favorites works in my app for up to 3 Favorites.  It's when I add the 4th in the vehicle as described above, I have an issue. This is in GM/Chevrolet's Executive Escalations department and they said this is a problem with some vehicles/users.  They don't have a resolution yet.
