Arena Mobile Bug?

Just had this happened. Playing Arena on my PC and Im already at 2 losses. I wanted to leave my house and continue the game on my phone so I just signed in on my phone, which obviously disconnected me from the PC client. On my phone it brings me to the main menu, so i click arena. Instead of putting me in my game it shows the usual screen (2 losses still there) i start another game, end up winning it, and when I come back to the arena screen it shows 3 losses and doesnt count the win I just made. What happened? And did the person I just beat get a lost?
