Sigue el mismo problema, ¿verdad?, ¿no han publicado un Hot Fix como en junio del año pasado?
Hi All,
Thank you for reaching out, and sorry about the trouble.
Please update the application to the latest version and check if the issue still occurs.
You may update the application by going to Help > Check for updates.
Please refer to the following page for more information on the latest version: https://helpx.adobe.com/acrobat/release-note/release-notes-acrobat-reader.html.
If the issue persists, please try using “Copy with formatting” instead of “Copy” from the right-click menu on text selection. Check if that works.
Let us know how it goes.
Thanks,
Meenakshi
