Text not showing in view until Text layer toggled off/on again

Same model (stage set for Under Milk Wood - UMW v1.5.1.skp) as in previous posts, apparent on both Nexus 7 and S7 Edge.

Text which is set to visible on Stage Plan scene doesn’t show when you first select the scene. But it does appear after you toggle the Text layer off then on again, and then stays visible after you change scenes and come back to Stage Plan.

Maybe the layer visibility isn’t updated when the scene is first loaded?
