Need the location of the clipboard on my iPad please?

The clipboard only contains the last copy you made. Each new copy replaces the previous one. The only way to see or access the last thing you copied is to paste is somewhere.

Essentially, the clipboard has no meaningful location.

The iPad clipboard is merely a temporary location for text (or objects) that you “cut” or “copy”. When you “paste”, the last item copied to the clipboard is pasted to the chosen location.

The iOS/iPadOS clipboard is not of itself an accessible location or App - neither does it maintain any kind of history that can be reviewed or edited.

To copy to the clipboard, highlight the text passage, image or object; from the menu, select Copy.
