Infotainment wifi

I have an Android smartphone connected to my DS7 infotainment through Bluetooth. However, when I go into the settings and click on the option to share the internet connection, and click OK, it reverts to the internet connection not being checked. Is there a reason for this? What do I need to do for the car to have the internet connection and the onboard apps to work?

Thank you in advance.

If I understood right, for build-in app work, u need to share Wi-Fi from your telephone to car. Make a hotspot and Connect car to it

I did that, but for whatever reason the apps are still grayed out.

And u have on your phone MyDS app?

I do.
