Missing Preferences Option: General - Open documents as new tabs in the same window
I know there is a feature under Edit > Preferences > General called "Open documents as new tabs in the same window," however, I am missing this option.
Is this no longer available? Is there an update I require to get this option? I used to have this option on Acrobat on my previous PC. When I received my PC refresh recently, I have found the option is no longer available. This could be an "older" option and may no longer be available but I want to confirm. I find this option to be very helpful and efficient for what I use Acrobat for. Thanks in advance for any assistance.
