My 3ds xl is really slow when I turn it on. It at least takes about 30sec to go from a black screen to the home screen after pressing the power button. Immediately after it goes to the home screen a pop up shows up saying that I have no sd card even though I have a 35 GB sd card that I’ve hardly used. Lastly after pressing A to the pop up, my 3ds xl is really slow it looks like lag. Please help!!!
