When submitting the form the reported mime type that is received server side is image/jpeg, which is not listed as an accepted format, the file data received is also jpeg not the accepted formats. If I have saved the files to the device from the photos app and use "Choose files", jpeg files are still selectable, but we do get the correct file data and mime-types for heic/heif, and png files. While there is a work around to get the correct file types we are looking for, getting people to do this isn't reasonable, the desired outcome for this would be if I as a user select a heic/heif for upload the system gets the correct file regardless of where the selection has been made, be this the photos app or choose files.
