Component broken and can't delete
I'm using 126.96.36.199
There is a component that is broken. There is no way to delete it, and you can't drag it onto a page. All linked instances are showing the red link icon.
The broken Link icon on a Linked Component means that it can't find the original doc for the sake of getting updates, but you should still be able to drag a copy of current Component to page. What happens when you try that?
In Assets Panel, you should be able to select the Component and fight-click > Delete . Is Delete not available or disabled?
