So, we have built the simplest "hello world" application, and when we view the canvas app in the canvas app builder it's fine, and if I embed it in a bit of standard Visualforce it's fine, I can see this simple "hello".
Even if I add this Canvas app straight into visualforce with the old
<apex:canvasApp> tag - it works fine. Equally, if I remove the
<force:canvasApp> and just put a noddy Lightning component in the page layout, that works fine...
Any input on experience with Canvas in Lightning is more than welcome!
