Weather Plus App does not work for me

Hello guys,
I downloaded Weather Plus app (3.2.0. version).
I tried to add the city, but app says "Add Failed! Please check your network!"
I tried all connection modes (Auto, TCP, WAP, WAP2), but it did not work.
I tried to add different cities, it also didn't work.
I edit permisssion to "ALLOW", but still the same problem.

Does anybody facing the same difficulties?

Try contacting the vendor. Could it be that the app is not supported in your Country?
