As PDF readers, we recommend these:

Free WPS version, good for Windows or macOS:

https://www.wps.com/

Sumatra PDF, for Windows, GNU license:

https://www.sumatrapdfreader.org/free-pdf-reader

Skim for macOS GNU license:

https://skim-app.sourceforge.io/

All these PDF readers are free and much better than Adobe Acrobat PRO.

Adobe has become a joke nowadays.
