In Thyng>surface mode, when you point at any surface, the green surface indicator should appear within a few seconds – it will initially appear as four green corners of a square. If you are running Thyng for the first time and viewing your first surface, and the green surface indicator does not appear within about 15 seconds, then try and view another surface – if the green surface indicator still does not appear after about 15 seconds, then please restart your device and re-launch the Thyng app – after restarting your device, the green surface indicator should appear right away! (Please note that if you have already seen the green surface indicator during a Thyng session, and have already placed objects onto a surface, then the green surface indicator will no longer appear for that surface – this is normal behavior – once you have started using a surface, you can continue to use it and place objects on it without seeing the green surface indicator for that surface).
