Sydney Pro network installation license disappeared

I have been using Sydney Pro in a Wordpress network setup. Now the license seems to be gone, I am not able to update and I am not able to clear the license key as there is neither a menu entry for the whole network nor for the site where I am using this theme.

Hello, can you please provide a link to an affected website in order to let me check it?

You can use some link shortener if you don’t want to leave the link to your site in this topic.

Kind Regards, Roman.
