So I found...
.If I disable webGL the text comes back to android
could you try that see if it works?
But then I made a default start up C2 project and put some text in and no issues. hmm
 right, I disabled one of my debug text boxes and all the other text boxes came back even when webgl enabled
so maybe that was causing issue or chrome on android doesn't like too many text boxes. maybe you have similar situation.
FYI the general advice is to use sprite font for text in game / app as normal text boxes will kill performance especially if they are being updated regularly.....
