Show animation while next layout is loading?

My menu layout takes up to 3 seconds to start (on mobile through CocoonJS Canvas+). In this time, I'd like to have an animation on screen that tells the player its loading. The problem is that the game freezes while loading the layout, so all animations appear still, and I'd be restricted to a static image. Also, it seems loader layouts do not work on Canvas+.

Anyone have any clever solutions or ideas?

I don't know what your menu involves but I would consider adding it to each layout, possibly on a separate layer and make it visible or slide in at the end of each layout.

i can´t get it working either.
