Not a big deal but it’s happened a few times randomly. When I switch out of MPQ but not close and come back later it’ll quickly play a short sound effect right as it pops open. I think it’s the sound when you add a level to a character.
I’m playing on Android on my OnePlus 7 phone.
I also had a sound bug, but slightly different and on iOS.
During a match I switched out of MPQ and returned a bit later. But after that the sound effects in MPQ were all cut short after they played for a second or so, making it really staccato like. Very weird experience. Could upload a gameplay clip if necessary.
