Hi @Kal_Lam ,
Yep i did other test with https://kc-eu.kobotoolbox.org this server works .
The steps were:
1:- I created an account https://eu.kobotoolbox.org
2:- I uploaded the same form there.
3:- In the application I have configured the server as you commented in this thread. Server configuration in EU KoboToolbox server
I understand that it is a server issue, since it does work on this server.
