So, if you click on a score to show it and go back, the status bar remains visible? It is not the case with my Max Lumi and the problem only shows within mobilesheets. I am on firmware 3.5 which is the newest available at the moment for Max Lumi. Maybe this is different on Max Lumi 2 or Tab X.

Yes.  However, a point to note, I have turned off fullscreen mode - I like having the status bar at the top all the time so I can always keep track of the time and the state of charge of my battery.  It's so small it doesn't take up enough screen real estate to worry about.

My firmware seems to be labelled as 3.5.4

UPDATE to the above, I have now experienced the same problem daniel was referring to.  I went into the display settings to see if I could replicate his problem by turning on full screen  mode and experimenting with hiding the navigation bar.  I was able to then replicate daniels problem.

I ended up having to exit MS altogether and restarting it to restore functionality.  

What I noticed though, while the problem persisted, was that the text didn't go to white on white, but some very pale colour on white.  Still impossible to actually see, but it was there, if just barely.
