I get all the time this really annoying "Not responding" notice and for a while Adobe refuses to open the file. As I work with lots of pdfs all the time and very often have to open and close pdf-files, this waits a lot of my working time. If only my employee would allow me to use different pdf-software. In private live I never ever would consider Adobe.

When you open any pdf for the first time, it freezes and says not responding. I have to open the task manager and close Adobe. Then if I open the file again, it is fine. Just don't know why it happens every time I open a document now. I've checked for updates and there aren't any. A fix would be great.

OMG, enough now, please fix this! I have to wait a minute before I can do anything after trying to open any document...

Never opens without an issue. Always says Not Responding. Really not good when you're trying to get work done. Stinks that I have to pay monthly for a product that doesn't work right.

Constantly freezes and rainbow pinwheel on my mac. Basically has become worthless. Try and find someone for support. Only support I get is when I get an email that Adobe is going to suck another subscription payment off my credit card or if I want to "upgrade." How can I consider upgrading if the basic program continually crashes?

Hi,
Would like a confirmation on the following. When you say "Acrobat has not been opened yet"

Do you mean the first launch after installation
or
Do you mean the first launch after a machine restart?

Thanks,
Vinod

This always happens: first time opening any PDF document (Acrobat has not been opened yet), Acrobat will show '(Not responding)' in title bar for up to 30 seconds, maybe more, but opening succeeding PDF documents is quicker. If I just need to browse a PDF quickly, I would use Edge browser instead--fast response time every time.

Sorry for the inconvenience, could you please share specific steps that causes the issue.
