Remote shutter not working on Snapchat specifically

Had no problem using iPhone 8 Plus with remotes on Snap chat, now I have purchased multiple remotes thinking one of them would have to work with Snapchat but they don’t. They all work with the other camera apps on my iPhone 15, just not the Snapchat app camera! Very frustrating, it also worked with my 12 mini no problem. But I get the new iPhone and this is what I get. Too much bs. I should be able to use a remote shutter button for all the apps with a camera that’s the entire purpose of the thing, apple y’all need to figure this out it is obviously on apples end not taking of it. Figure it out already please like yesterday! More like 1 year ago.
