Acrobat Pro Combining PDF Bug "This feature is not included in your current Acrobat license."
I get this random bug every now and then on the paid version of Acrobat pro where when I go to combine files and make them into a PDF, I get a pop-up that says "This feature is not included in your current Acrobat license". When I go to do it a second time, I'm able to combine files. Kind of a strange bug, but it always works the second time I try and do this.

I’ve seen that annoying pop-up in Acrobat Pro about licensing when combining files, even on the paid version. If you want a quick distraction while dealing with it, try https://plinko.ci/app. The feature usually works on the second try, so it might be a glitch or a slow license check. It’s a minor hassle but easy to work around once you know.
