Enfocus Community

Today I get a notice that Enfocus send out an update for the Acrobat DC problem. But it only solve the problem if you have the 21.0.3 update. I've only have the 21, and I can´t see any update for that.

No you misunderstand. The update is called 21.0.3.
It is an update to version 21. So if you have a license for PitStop 21 you are good.
Just do the update and off you go!
