I thought Google Photos stores the .heic format and Apple always converts my SE2020 to jpg https://www.google.com/search?q=heic+app+iphone+photo
I am really wondering what you are doing as i do not have any problems with any apps wich .Heic format If it does not work ik automatiscally converts it.
.HEIC has license problems, patent problems as far as i know.
support uploading in this format.
