I having a problem while trying to login with line app. As our service is to provide Engagement Portal (FYI, it happens when you connect WiFi then it will prompt a page with advertisment and survey form. After you submit the survey form then you will get internet access OR you can choose to login with LINE). And so, we need to whitelist LINE url so that user can perform login with LINE APP.
But unfortunately, we unable to capture all the URL call to perform the action. (As some action is perform during the app).
So my question is, is there anyone know all the URL needed to whitelist so user can perform sign in with LINE APP?
Current scenario when without network scenario, iOS - unable to open LINE APP Android - able to open LINE APP but stuck on loading verification.
