Disconnecting after victories making them not count.

I have had 5 examples now of winning a game specifically in champs and as I click advance it doesn’t take me back to the correct menu instead disconnects from your services and counts it as a loss. I lost 4 champs games that I actually won due to this issue. Is this a joke? Am I getting hacked? It happens at the exact same time every single time. But when I lose it doesn’t  usually disconnect at that menu….  It’s honestly infuriating that this continues to happen. What’s the point of playing if every game is a loss because I disconnect and my wifi is solid. Doesn’t happen for any other game.
