Same issue as original poster. Moving back down to v611.1 to try and create my new array. I was banging my head against the wall trying to make things work!
I expected that. But, unfortunately, it's not appearing on 6.6.1.
Great tip! Clicking the icon on the plugins tab worked and took me straight to the File Activity UI.
I know there's an easy answer I'm missing, but...where's the button to use this plugin? I checked settings, tools, etc. and can't find it.
I'm on 6.6.1. Thanks!
