Ok. I had it added into the scene but it was manually without using the prefab. Now with the prefab I have the callbacks.
Here is the result I have :
url : (null)
Error : Error Domain=WebKitErrorDomain Code=101 “(null)”
I check before calling InAppBrowser.OpenURL() that the url string sent is not null and valid . I’m sure the problem is not with the url because I can have the same url loaded without problem and then having trouble with it another time.
