Ever since the update a day after, the speaker icon 
stopped using the voice to read it back to you in the desktop shortcut to the chrome site of chatgpt 4, the option for 3.5 disappeared, and there are intermintent network 
issuses with the magic button on android. And like you are sharing the microphone 
goes in an out. Window 10, chrome, android. Hopefully the fixes will be addressed soon.
