Unable to turn off Reflow

Same issue — and I would like to add reflow only gets stuck on some pages of a document, but when it does it permanently alters the structure of the page, even when I open the PDF in other programs.

Same issue here. 

Note that while I have the required system access to execute the 'preferences reset' workaround, most organizational users won't - & e.g. for people doing accessibility remediation on PDFs, this means they will require an entirely different Windows user profile in order to check reflow display of the documents they're working on. So as a workaround, it's more or less unworkable for a large segment of users. 

Hi there 
 
Hope you are doing well and sorry to hear that
 
Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check. If the file is stored on a shared network/drive please download it to your computer locally and then try again.
 
As you have the recent version installed, please try to reset the Acrobat preferences as described here https://adobe.ly/4bQUuss and check
 
You may also try to create a new test user profile with full admin rights or enable the root account in MAC https://adobe.ly/3yEV3GP and try using the application there and check.
