I send DAIL request but lg not launch my application in tv.

For security reasons, we do not currently recommend using DIAL on webOS TVs. So we don’t provide any guidelines on this. If there are any updates, we will let you know via this developer website. Thank you.

3

I appreciate that, but can you just tell me why the app is not launching? I need to launch and use it in my application. Can you tell me where I should ask this question or where I can get this information if I need it?

thank you for support

As mentioned above, we don’t provide any guidelines on how to use DIAL on webOS TV. Sorry for not being helpful.
