How to get ACR to ignore crop exif/metadata from camera

Hello. A few people have had this problem in the past, with one old solution being a LR plugin that no longer seems to exist. So I'm stuck

My Canon camera's aspect ratio is 3:2 and all raw files are saved as such. I had cropping on camera at 4:3. Even so, the camera still saves the raw file as 3:2. I have "add cropping information" OFF on my camera so they should appear as 3:2 on Adobe apps. However the raw files are opening as 4:3 in ACR/Photoshp/Bridge. I've opened one such .CR2 file in RawTherapee and the extra pixels are there (but I'd rather use ACR to edit). So I think, on opening the file, Adobe is reading some kind of crop prompt and I can't find anywhere to stop it from doing this. Nothing in the crop panel of ACR, nothing in metadata I can change. This should be so simple! Please help 🙂

Please be aware - I don't really understand exif data - I'm not tech-minded 😕😕
