Can't fetch images - fetch button doesn't appear

Hi! i smushed all my images and received the notification email that says my files are ready, however, the fetch button doesn't show up and i can't get my images.

I receive this note:
A recent bulk smushing request has been completed!
Visit Media » WP Smush Pro to download the smushed images to your site.

When accessing WP Smush Pro - it still offers me to send images - this request also won't go through, it'll say: Attachment data missing, request not processed by API

Thanks for the help!
