I will take a look as I do a code review, but somehow you’re the only one who has had issues, maybe you need to use a TOR bridge? Looking at the logs only one slatepack failed to decrypt, you might have been the unlucky one also. Before submitting them make sure there are no leading or trailing whitespaces in it. I use Debian with GNOME desktop and the copy and finalize functions were working just fine on my end. I don’t have a Windows or Mac computer to test anything else unfortunately.
