How does czternaście become czternastu here? I find the numbers really difficult
Links only work some of the time if you use the app. I suspect that it only works if you just type the URL rather than use proper HTML. This is of course a bug in the app but naked URL's could be a work-around (you should probably check my conjecture first though).
I also have that problem with links and the app buy luckily have since worked out what's going on with czternastu. Thanks guys!
