The use of the word "copy" instead of "text"

Is it correct to use the word copy instead of the word text in some contexts?

For example, the titles of two tasks were as follows:

Update log out copy in the profile menu

and

Copy for notifications

Which respectively means Update the text of the logout button and List of texts for notifications

For me, the use of the word copy here seems a bit strange and somewhat incorrect, however, I was not able to find any source on the use of copy to mean text.

Edit: I was referred by my colleague to this link, specifically to the "written text that is to be printed, or text that is intended to help with the sale of a product" section. However, I don't personally believe this is the same use case.

Solution 1:

It is correct to use copy to mean text in certain contexts, such as advertising and in print media.

Your colleague cited Cambridge:

text that is to be printed, or text that is used to sell a product: She writes advertising copy.

Consider your first example.

? Update log out copy in the profile menu

The text (not copy) will appear on a computer screen, not, say, for a printed newspaper or magazine. So in this context, the words are not interchangeable.

If you were working for an advertising firm or a magazine or a newspaper, someone might say:

Submit the copy / text for the coronavirus outbreak by noon, or you're fired.

Either would work.

But for a non-print medium, someone would say:

Submit the text for the coronavirus outbreak by noon.
