I have 3 TVboxes and they are different brands , and the problem that I have is this . I have down loaded the 3now app on all the boxes ,1 works fine and the other 2 I get the following message "Sorry this app isn't supported on jail broken devices."

I have also downloaded the TVNZ app on them and it works perfectly . So what/how can I fix this ?

The boxes that I am having the problems with are :- X96 Mini Android 7.1 Smart TV Box and a S6 Pro RK3229 Smart TV Box . They all run on the Android system and also have the Koidi System preinstalled
