Can not open design library now?

can not open design library now? click the cloud icon, nothing happen
or only me met this?

The first icon is the design library.

Clicking the icon works for both the post editor and the site editor here. Perhaps there is a configuration, other plugin or something else affecting this in your environment.

What @StrangeTech said.

It would be helpful if you could check your console for errors when clicking the icon.

sorry for delay reply. after i deactive and reactive plugin , it’s work as normal. thanks for everyone’s help.

now i found this library can not click ONLY in themer Templates pages.
