TLDR: I can't scroll at all using my laptop's trackpad in Acrobat, the keyboard works fine. Please don't ask me to disable my touchscreen as its's an extremely tedious process. I also connected a mouse, the mouse works fine, but in the case I don't have a mouse and need to access PDFs, someone please help. No trolls, thanks. I'm tired of trolls.
When I scroll, it shows the preview window at the side like shuddering up and down? and when scrolling up, I can only scroll one page by one page. Down scrolling is literally impossible. It was working fine yesterday, and for almost a month plus? since I got this laptop. I've restarted my computer, and am going to uninstall, reinstall acrobat.
My computer is a XPS15, 2017 edition.
I, obviously, can't reproduce your problem. I can only suggest... In Preferences -> General try setting the Touch Mode to "Always".
Does this issue only effect Acrobat? Is this behavior constant from file to file? If you have Reader on the machine as well, I would open the same file up to see if it behaves similarly.
