my app using FCM and pushy to deliver notif at the same time, the situation that is happening now is that I am getting two similar notification banners. How do I delete/cancel one of the notification banners when one of them has appeared. How do I handle this on the frontend side? If it is not possible/not recommended, can you please provide documentation from Apple so that it is best to change it on the server side

Since updating my iPhone to iOS 17, I've noticed that my apps from the App Store are consuming an excessive amount of storage space (for example: when I used it for a few hours, it took up 3GB of storage) . This issue didn't occur when I was using iOS 14, 15, or 16 (I just tried it on several devices, with the same application and version). Has anyone else encountered this problem, and does anyone have suggestions for identifying its root cause?
