Is it possiblt to have turned off the "Undo" command for plugins?
 

If I start a new session, I can't undo any moves that I make with plugins. I've tried different types of plugins and different plugin companies. The weird thing is that if I open an older session, the older session plugins will undo with no problem. But, if I add a new plugin in the older session, the new one has the same "can't undo" issue. Any ideas? Thanks!

Never mind, I just figured it out. I'm posting this anyway if anybody else has this issue. For whatever reason, I think when I installed my new Universal Audio interface drivers,the "Plug-in controls default to auto-enabled" became unchecked. When I checked the box, it fixed the issue
