iOS
Siri will not work through your buds (via Tap Touch) while you are streaming from the IQstream TV. However, you can still use Siri on your phone.
If you want to use Siri through your buds you need to switch your IQstream source to be your phone. Please note that you will lose the streaming connection during this time. To re-establish the connection, switch the source back from your phone to your IQstream TV.
Android
