Just some info here, because I know you have a script reply for this type of thing. But please pass this on to the team. These issues have happened in the past week or so (though similar have always happened.)
Sitting next to my son on the couch doing a friendly battle. Same WIFI, same type of device. I disconnect in battle, he does not. Pandora streams uninterrupted in the background. An hour later we try again. First battle goes nicely. The second time he disconnects and I do not.
I have excellent data reception in my office at work. I will battle during lunch, and get 3-5 solid battles in with flawless execution. Then, randomly, I will disconnect or I get the beginning screen for an eternity while the battle rages on without me knowing. This happens frequently. The connection is fine. Solid. I never have any issues on any other game.
I won’t even pretend that this type of game will always have a perfect connection. But many, many times it’s exceedingly obvious the device or connection is not the issue. It’s not customer service excellence to keep tossing out solutions for OUR end. Even if you can tell us - Hey, we’re 98% good here, but, yep, we drop it. Owning the problem will go far.
