I get a kick when those people show up here telling us to quit using whstsapp., and give a privacy / security spiel we all know about. I would highly bet, that most of us here, would LOVE not to use whatsapp, and would also wager that , most here, try to convince our contacts to get on other apps like Signal. I for one, like somone else mentioned, have a lot of friends on whatsapp. Furthermore, what should I tell my Doctor? To use signal if he wants to continue having me as a patient? What about restaurants? You're going to have to switch to telegram if you want me to continue ordering from you. The bottom line is you can likely ask people to switch, but you cant force them into it, and if they reluctantly switched for YOU, they are likely not to be as attentive to your messages because they wont see them.
This Microphone bug, has nothing to do with whatsapp. When I send an audio message, I can confirm that the MIC stays on for whatsapp, telegram, and Molly. The only way to turn it off is to just turn off the mic, but it still annoying. I hope its fixed soon.
