Question Objects appear in Editor but not on phone

Hi
Apologies for the lack of detail but I don't know where to start
I have a fully functioning scene but have recently added a basic HUD to control the player. When I run the scene in editor it works fine but when I load onto my phone the HUD doesn't appear.
HUD

Inspector

I have checked the obvious; that it is the same scene by editing another object and this is reflected when I load on my phone. But no sign of the HUD

Any ideas how I can track down the problem?
thanks

 

It is likely a scaling / aspect ratio thing and can be addressed by tweaking your UI.

Here are some notes on UI Anchoring, Scaling, CanvasScaler, etc:

Thanks but this is in 3d (Google cardboard) is that still relevant?

 

Can't imagine why it would not be! It's the same UI system, it's a screen, it behaves according to well-defined rules.

 

thanks - reduced the canvas size and that seemed to fix it
