We are updation Storyous app constantly as we are adding new functions. The possibilty to update appears after login as a text ,,what is new in POS/Vylepšili jsme aplikaci Storyous". If you have no time for the update, you can update it later again in centrum pomoci - Aktualizovat aplikaci. We highly recommend our customer to make the update regularly. And have the same versions on all tablets.
