Team calls not ringing on Mobile app anymore

I’m using Teams on both my laptop and iPhone, and when I received calls it used to call on both at the same time, given I was logged in both places. It has however now suddenly stopped ringing on my mobile app, and only comes in on my laptop. Which is frustrating as I would like to have the opportunity to choose where to take the call from.
How do I change that so I get call simultaneously on both devices again?
