Make sure you use the real "N" key and not "Ñ" (this is a known limitation that has been discussed earlier, and I have some ideas on how to fix it). If it still does not work, send me your language files and logs (you have to enable them in the application and they can be found in ~/.local/share/okboard). And do not expect a quick answer (I did not even start to work on the weeks old transparency issue). BTW, last week I worked on the engine that processes swipes. Now it is not that much more accurate, but it does no more assign bad scores to expected results. Next week I will start to re-implement the prediction engine (this is the part which handle language model and learning. At the moment it is completely broken) and after I will go back to regular bug fixing.
