Android Auto works on wifi but not on mobile data

I have two phones, a Galaxy S5 and a new Galaxy A50. On both of them I can listen and communicate via wifi but everything except the navigation goes offline when using mobile data.

Is Android Auto allowed to use mobile data in the background? What about the apps that you're using, do you have issues with those as well when not using them through Android Auto?

After hours trying to solve the problem, it turned out to be a simple fix. When I moved my sim to the Galaxy A50 and put a new sim into the Galaxy S5, my provider did not reset the data on my account. Works like a charm now!
