I would like to inquire about replacing the featured image.

hello.
I think it’s a really well-made theme.
Today I am making various settings.
While I’m setting up in the office, I’m editing content and changing featured images. It was nice to have the ability to search free image sites in real time and apply them right away.

But when I got home and tried to edit the content and replace the featured image, all the features I had seen at the office had disappeared.

I would like to inquire whether there are any limitations to the function depending on the Windows and Mac OS environments.

i found it

Found it.
It was a permission issue.
