I use the iCloud Photo Library and wanted to upload some HEIC images from my Mac to the iCloud via iCloud.com. Unfortunately, all the HEIC pictures are "greyed out" and not selectable in the finder tab that opens to select the pictures. I tried it with safari, firefox and chrome.
When selecting "import" in the photos app on Mac it works but I do not want the pictures marked as imported.
As there a way around this?
