I have attached a screen shot of my latest version of Acrobat, I have searched and searched in the program and online and cannot for the life of me figure out where the undo and redo buttons went and Ctrl+Z doesn't seem to be working either 😞 Can someone ls help? Thank you so much!
Press Alt to show the menu bar, and then look under the Edit menu (NOT under the Edit button in the top panel in your screenshot). Note that not all commands can be undone, though.
