Can't select text by moius double-click

If a user browsing App using “Full Screen” option, nothing gets highlighed when double-clicking on text!
Same thing if browing via mobile. Only thing possible is to paste text in search field.

How can this be activated?

Certain components will let you copy the contents of that component if you long press And select the copy button.

Not working for any displayed text for me ! Here’s an example.
I can’t copy any of such presented display

Ahh, I can’t either on a basic table. Like I said, only certain components, like basic text, and probably a few others. Depending on your situation, you also have the option to create a button or action text, or anything that let’s you set an action of copy to clipboard.
