This happens every other day or so the store just randomly opens up to the MPQ page, happens the most after a match ends and when hitting the next button the game redirects to the store.
Did you lose the match? Because the option for “improve your roster” that is where the “next” button normally is… is the “shop” button.
I think they mean the Google Play store opens. It’s been happening to me too.
I find it happens most often if I don’t clear the Google Play store from my recent apps after updating MPQ. That said, it happened after I installed the latest update, even tho I did clear the store.
I see what you mean. It’s happened to me twice since yesterday.
