Hey there, thanks for the feedback. Can you tell me which version of the app you are having trouble in? I just released a couple of updates (v1.5.3) which addresses some of the issues. The language selector is in the settings. I responded to another post about this so maybe this is the same issue? I'll post a screenshot. You have to open settings and scroll over.
Regarding the text field issue, please let me know which version of the app you are running (tap the i and it should show you) so I can see if this a recent problem. I addresses a bug like this a while back. I've been working with a number of publishers around the Mythic brand in different languages and hope to be able to add official tables and language content. I was able to do this with Portuguese but unfortunately for Italian and Spanish, we have not been able to work it out yet. Hope this helps! Please let me know what I can do for you and your friend.
