Sprites do not show

Sprites have become invisible (even in a tiny testproject to diagose the problem). Also tested a public project (Flappy Ball) and no sprite to be seen… I must be overlooking something, but I had no problem in the past, and I spent all day trying te resolve this one, but to no avail.
Live test and apk file install have the same effect.

Have to tried to re-remix the app for a fresh start. It could be an issue with your phone?

Tried another Phone, and it works! Tried again my regular Phone and it does work now!! Dit not reboot or anything… quite mysterious.
