Did they seriously take away batch editing capabilities?

[Nicanada]

After computer crash I now have the most recent version of Lightroom classic.  I have just edited over 100 photos for a client, and have them exactly the way I want them.  I always submit a black-and-white version of each photo as well.  But surprise surprise I am no longer able to convert each photo to a black-and-white version (via a preset) in under five seconds .  Did Lightroom seriously take away the ability to batch edit all of my photos with only three clicks?!  Please tell me there is still a way to do this, otherwise this is going to take me FOREVER!!!

No, the capability still remains in Lightroom-Classic.

I can convert multiple selected images to B&W in the Library Grid with one key press- [V]. (Export  as 'mono' then restore to color with [V] again!)

Also in the Library Grid, you can apply a saved Preset in the Quick Develop Panel.

Or in Develop module-

Create a Collection of Virtual Copies and change all selected with a suitable B&W Profile.

Apply a B&W preset and Copy&Paste to multiple selected files. (or use AutoSync)

"the most recent version of Lightroom classic"  

Most recent really means nothing unless you confirm this by posting a screenclip of the MENU: Help > System Info....

I am not sure I understand what you mean by "I always submit a B&W version of each photo".

Did you do that by creating a Virtual Copy of each photo and then make that VC a B&W version?

The only other way to get one color and one B&W version of each image is to Export each image after make the B&W convertion and then Reverting that B&W convertion to get back to a color image.

What was in the preset you used, what steps did it include? Why don't you use that same preset?
