Opening other spotify clients sometimes ask Continue Playing

Hello, when trying to control librespot from other clients, it sometimes ask "Continue Playing" and the current session (song) continues. It automatically connects when this "Continue Playing" pops in the client.

The problem is when it doesn't, and I try to select manually the session stops

This is the debug trace when this manual selection and session stops:

Any idea what could it be?

Reproduce the manual client selection and start with the librespot_connect::discovery and librespot_connect::spirc paths shown in the trace. Follow the Session and Player shutdown and recreation messages to identify what happens during selection; done means manually selecting the client no longer stops the current session, with the behavior verified against an equivalent debug trace.
