Noise cancellation is not working

Hi team, 

The noise cancellation option which is not working properly. If i enable the noise cancellation option there is some more glitches and more noise added to my source. If i disable that option the audio was clear.  It's annoying na.. we are paid for your premium subscriptions. Ensure Every option is working fine. another one issue there there is a sync between device and cloud it's not working.. leads to slow down. Hope such issues are resolved in future!!!!
