Why would an iPhone 6 not copy links?

[Evilguppy]

I'm trying to help a friend.
She says she long presses a link on her phone, gets the "link copied" pop up but then it won't paste.
What would cause a 6 in good working condition to do that?

Where is she trying to paste the links? Some places won't work. See if they paste in the Notes app.

I'll ask her, thanks!

When I long-tap a link, I get a popup command to copy the URL, not a message that it has been copied.
