P: File > "import from iphone or ipad" not active

What does Apple's text edit have to do with PS's "File>Import from iPhone" function greying out a user's iPhone" ?

Well, to start off with, since adobe can't be bothered with creating a proper users manual, finding information about how to use ANY feature in PS is catch-as-catch-can.  The help system is almost always useless, the adobe webstie information only addresses very basic things, and adobe's support is ALWAYS utterly useless.  And that leaves guessing.

So  I GUESS  if PS was connected to my camera so it could do whatever this function is supposed to do, my camera listing in "File>Import from Phone" wouldn't be greyed out.  But it is.

I have ensured PS and my LrM camera are both on the same WiFI (in case it connects via WiFi - which, of course, I have no way of knowing since there are no instuctions on how to use this) and I have connected my phone to the same computer running PS via a USB cable and ensured the computer was "talking" to the phone.  Still, the phone is greyed out.  Since it's greyed out, there is nothing further I can do to play with the feature to try to figure out how it works.

I'm using the latest version of everything except MacOS which is running Mojave.

What exact issue are you seeing? Are you seeing it work the same or differently from an Apple app like TextEdit?

I don't think that is supported from the feature. Try Apple's text edit. It only allows the same 3 option as Photoshop.

To Jeffrey Tranberry - It didn't.  And, there have been more updates to PS and I STILL have this exact same problem.  Would be nice if Adobe actually fixed something - ANYTHING - once in awhile.

Did anyone get this to work?  I reset my preferences but my iphone is still ghosted.  I can take picture through that menu, but won't let me import an existing photo on my phone.  Thanks

You probably have to ask Apple, because this seems to be an Apple functionality that Adobe just hooked into. There are other ways of getting photos from your iPhone to your computer (and then into Photoshop).

But then what's the point of importing from iPhone if the only option is to take a photo after you're connected to Photoshop? I don't want to import photos of my office, I want to import photos I've taken elsewhere! 

I believe the name is always greyed out. It’s just to tell you which device it is, in case you have more than one device (see the screenshot of Pages).
