Hi,
I have a problem with my Shapes. Independent which scene is active, all Shapes are shortly flashing white (well, one is flashing blue, all others are white) every 2-3 minutes. After this they are normaly back in the activated scene.
I've tried everything, even a hard reset, but nothing changes…
Do you have any idea what I can do?
