I have a problem – Stick Nodes Pro - Animator Review

When my friends send me their stk it says error cuz it said its not a valid stk but it is! After that it says please check if your stick nodes is up to date but when i check it in the app store it just says open!! My version i have right now is 2.3.6 it was updated 2 months ago because i couldnt update it!!! I think its because im on iOS but this is a good animating app!!!!!
