we checkout Cobalt 10.49488 and modify some codes that pass URL to cobalt.
we check RC_9 release note, it should apply DIAL 2.0 smooth pairing.
so we can deliver "https://www.youtube.com/tv?wired=1&pairingCode=9613cf31-19c5-4045-8d41-0b4d18ad2330&theme=cl&additionalDataUrl=http://localhost:55868/dialData?app=YouTube" to cobalt "BrowserModule::Navigate()" for smooth pairing.
then Youtbe(cobalt) will pair with my smartphone, smartphone seem it work properly also.
after we check the dial flow, we found we did not receive "/dialData" and "screenId".
could you help us check our implemention about dial smooth pairing?
or an exmaple?
