To repeat:
in an open passage list, click on add from clipboard
I think you mean in an open bibligraphy document
And the help file states:
• ... clipboard – cites the last resource that text was copied from.
Logos Help (Bellingham, WA: Faithlife, 2022).
So this seems like it is behaving as expected as you aren't copying text from the resource, simply copying the citation.
I think you mean in an open bibliography document
Yes ... my mind only moved half way from one topic to the next. [:$]
I think this is sloppiness in the definition. Throughout Logos "copy" means "copy to clipboard" on a PC. I don't know how copy works on a Mac.
