Yep, I failed to mention that. I’ve been able to put a new app on a menu, open it, and add a layer. And other things like import/export/delete seem to work.
But I wanted to edit the base of this new dashboard I was working on instead of adding a layer, and don’t have a workaround for that. Ah, well.
I was getting this something similar - figured it was just me. If I run Application Studio from the client, and try to open a layer, it just sits there and I never get the app studio developer to open. If I run Kinetic from a browser and do the exact same steps, I’m able to open up the base layer in app studio. Figured it was my motivation to start running the browser anyway.
