I’m playing on my little iPhone and in the lobby for valley of the gods bosses the “leave” button is right where notifications pop up. I went to dismiss a notification and accidentally left the lobby which I’ve never done before. Considering it destroys your key to enter there really should be a warning prompt and a confirmation to leave. Seems like a super easy fix.

If you use a key to enter a lobby and leave the door is still open for that boss unless you open a different door
