Thank you for the detailed response and thorough troubleshooting. I followed the official instructions and included the files in my theme. Everything works as expected and the nag is gone. Thanks again.
Is there still no solution for this? Would love to hide the update notice.
Thanks for the quick turn around. I’ll let you know if I see any other errors.
I’m using the latest version in safari. I double checked in firefox and chrome and the preview images are a displaying ok. Looks like it’s only safari.
Thanks man.
