Unable to upload from Photos to iCloud.
I've just started to sync Photos with iCloud on a Mac running Catalina. Thousands of my photos are unable to upload. They are all jpgs that originally had RAW files attached, but the RAWs were deleted. They have the J in the corner and won't upload.
I've already rebuilt the Photos library to no avail.
I've tried exporting and re-importing the photos. The export gives an error that the RAW file wasn't found, but exports the jpg fine. On re-import it still shows as needing the RAW file!
