I'm using the ESR MagSafe wallet which has the bonus feature of working as a kickstand. You can place your phone vertically or horizontally. That said, the camera bump on the 15 Pro is so big that with my case on, the lip prevents the wallet from fully attaching in horizontal mode. It's a minor inconvenience and probably wouldn't exist without the case, but still worth noting.
