Thank for this amazing app.
I use MDPro3 v1.2.2 on Android, mainly duel with bots. Solo mode sometimes does not release port when switch bot or after a duel.
To reproduce the error: click SOLO, double click on one bot so enter a room, go back to SOLO, now the port occupied, this can be workaround by changing the port but it is very inconvenient.
And could you please make the bot ask for a rematch after a duel so don't need to create the room again, I see YGOPro has this feature.
