Hi everyone, I have about 15 different stacks for more than 200 notebooks. The stacks help me keep a massive amount of information organized. I use Evernote on MAC v1.42.2. It is incredibly frustrating that I cannot search a stack in the stack search pane to quick pull up a stack so I can find one of the 20-40 different notebooks that might be in it. The whole "stack:"xyz"" does not work for me nor do I see that as a valid solution. Please, does anyone know how to easily search for a stack through which you can click to find your notebooks? Thank you.
