The option to save as PDF is gone in the new update. When I uninstalled and installed the older version it's back. Couple updates ago there was a problem with editintg CMYK files. What's up with these updates lately?
And if anyones wondering it's definitely a bug or they removed it from Save As on purpose. 8 bit file, file size wasn't too large, and the same file saves as a PDF just fine on previoius version.
Adobe changed "Save As..." UI in 22.4 "Save As..." now has a Button for "Save a Copy..." the new Photoshop File menu item "Save a Copy..." shortcut Alt+Ctrl+S you may need to renove " copy" from the File Name to save the PDF file name you want saved. Adobe's "BS" for the change is it protects you work you have to use a new interface to save what you want to save,
