This happens all to often in Adobe products: everything is hyper conditional. I'm trying to learn a new Adobe app and I search for tutorials online (or even use some tutorial provided by Adobe). Then I start the tutorial, an option covered in the tutorial is GREYED OUT, and no explanation or contingency reference is offered.
I've NEVER USED THIS SOFTWARE BEFORE. WHY WOULD A BASIC FUNCTION BE GREYED OUT ALREADY?
Even if Adobe has a perfectly reasonable reason why this is the case: PLEASE TAKE THE TIME TO OFFER GUIDENCE FOR THE PEOPLE WHO MIGHT BE STARTING WITH A GREYED OUT MENU. It's not an OUTLIER issue: stuff like this happens ALL THE TIME in Adobe products. Please adjust your instructions accordingly.
