I am currently using Adobe Acrobat Pro Version 2022.003.20263
It is running on hardware that is up-to date and win 10.
the program struggles to even open smaller pdf:s (say 300kb) and once open there is another pause before being able to scroll the document. Almost improbably sluggish overall. Scrolling can initally be quite not-so-smooth. However, once it is 100% loaded I think it works just fine. Earlier versions of acrobat did not have this problem, running on the same hardware.
The same pdfs can be open and viewed quite swiftly on other software such as outlook and chrome.
