I have searched this issue on the community and haven't found an answer. Two days ago, Acrobat DC opened all PDFs in tab view. Yesterday, it stopped. When I go into Edit: Preferences: General, I do not get the option to select / deselect "Open documents as new tabs in the same window" as others have suggested. Please help!
Are you able to combine the tabs into one window in the usual way (by dragging the tabs, just like in a browser)?
There aren't any tabs available. I used to be able to combine windows / tabs similar to Chrome, but now there's no option for tabs.
I wonder if you could check for me the version of Acrobat, as shown by Help > About Adobe Acrobat?
We're looking for a long string like "2016.123.45678".
Here it is; thanks.
Ok, I can't explain how it happened, but the app you are running today is "Classic 2015" version of Acrobat Standard. You need Acrobat 2017 or later. If you have a subscription, you have got the wrong app, because a subscription can be got right up to date. It's hard to think why your software would have gone to an older version, since this worked a few weeks ago, unless you or someone else reinstalled it, or this is a different computer.
