At first, my camera was just broken. I have the Instax mini 9 and I dropped it a couple of times and it was working after that but I have a photoshoot tomorrow at school and I went to get the camera that I haven’t touched in so long and the red light was just stuck there. I replaced the batteries and did everything I could and spent 2 hours fixing it. Then, I took out the batteries and switched them and opened the back. It started whirring and it took a picture. The light starting flashing again and now it works. Hope this helps!
