Wondering is anyone else has had this problem? I made selects by tagging. Then copied the files to a new folder using Copy Photos (delete originals). All the tags were undone in the copied folder. If I just copy a file and not check the box to "Copy Photos (delete originals)" the tag is still there in the new folder. Not sure this is a new feature or a bug? Thats all :-)
I did update to newest Catalina 10.15 this morning :-)
