Good Morning,
I'm the head of our IT-Department.
In our Company we are facing same issues with Version 2019.008.20074 in pro and standard version with about 700+ clients. Sometimes it's just hanging other times it freezes and you have to delete the task in task manager. There's no error code..
We found out that one plugin (ia32.api) is causing the problem. We think that this plugin tries to access internet. If we disable the plugin the error does not exist but then you can't print or comment the pdf-file.
In a process monitor you can see that Adobe Reader process tries to connect to amazon web services.. Policies in our company dont allow to communicate to cloud services.
We really need a solution here!
