Huge resource hog and cannot export Combine PDFs. Go to save and a blank window appears. Adobe DC is a piece of garbage. I've seen nothing but problems after XI. It's gotten slower, more buggy and the interface and process of using is even more cumbersome than ever. If your idea was to cause more users to spend more time on your software... good job! Mission accomplished! Now I need a solution since you've totally ruined me being able to use it for anything. Oh, but I pay for keeping it updated.
