Hi,
Thank you for reaching out.
Regarding the filter on the Media Library when you are not able to see the error images or the optimized, unoptimized, this is related to an error that sometimes might occur and it is some unknown conflict. We are not sure where it might be coming from yet. We will have to investigate it further. The fastest way we use in these situations to find the error images through Media Library(List View) is to use Screen Option (top right position in Media Library page) and display 300-400 images per page – then it’s a bit easier to scroll down and search.
Please note that in some cases this kind of issue might be temporary and they need their own time in order to be fixed.
You may refer to this document if you are experiencing issues with optimization: https://imagify.io/documentation/optimization-is-stuck/
Best Regards,
