It didn’t work here. The microphone button doesn’t show up to switch to voice. And I’m on version 445 from TestFlight.

This is only for replying to voice messages. Before, you could only reply with voice, now its also possible to reply with text.
And how Could I send a voice message?
Tap mic button. If you don’t see it remove existing text and close new post screen first because the button will disappear once text is entered
Veja que aqui não aparece o botão de microfone.
