We are not all lucky to be able to make each session or appointment
We are almost on 2020 and 99.9% of us have a smartphone. It's not so difficult sending a message via xbox app or in the site to inform that you are late or not available.
If the reason of yous absence is "overstepping", well, I don't understand why I can't give you bad feedback without worrying about receiving a bad one too, despite all my effort to contact you and make the session possible for the other players.
EDIT: anyway, I'm talking in general, for whatever reason you (and all the team) could have to give a negative feedback to a bad player.
