Mobile browser - Messages and Video and Audio enable

On A mobile browser - Portrait mode the audio and video buttons does not work properly and it sometimes does not work to mute and unmute easily . Landscape mode is perfectly fine but Portrait mode throws few issues and it does not work as it work in landscape mode.

Also some of the messages just stays as is and does not go away . for ex mute /unmute message would always be next to microphone icon . Any guidance how i can correct this?!

@corby I was pointing to this issue in my previous message
