Hi
I am not sure if this has been discussed before, in WhatsApp you will have no feedback of typed characters and words using VoiceOver. I found that if I toggle an option to have popup alert in WhatsApp VoiceOver seems to read and announce typed words and characters. So if you are in a WhatsApp message, and you need to get feedback for what you type, then go back to the main whatsApp screen and swipe on any message thread, choose more to summon alert popup screen. Cancel this and then VoiceOver will announce everything you type as normal.
