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, but after reinstall on new system the app again copy number, I cannot change this when using iOS app (I have numbers in a middle of sentences when annotating fragments on iOS)
Cropping pdf (as someone from support suggested it) doesnt solve the problem
