I really often read articles as preprints (not yet published by scientific journal), many of them have number along every line of text (it should help when making review/technical correct).
Most modern pdfs readers doesn’t copy these lines when copying text. I managed to change the default behaviour on Mac (so it now doesn’t copy it), but I cannot change this when using iOS app (I have numbers in a middle of sentences when annotating fragments on iOS)
Here is example pdf
How to change this behaviour, so the numbers stop appearing?
Below example how bad this is from my app.
