I’ll add my two cents, I have mild tinnitus on the left ear, like other readers I learned to ignore it and only really notice it when focusing or drawing attention to it. Luckily doesn’t affect my sleep or work. Stress and similar situations seem to intensify it a little and I become more aware. I’ll add a curious one to the discussion, I’m a big AirPods fan, as soon as Apple released the AirPods Pro I bought them, on the first week of use I started getting horrible headaches/nauseas which I associated (most likely wrongly) to having tinnitus and it causing some balance “imbalance”. Returned them and got back to regular AirPods.
How can you guarantee this? And how about received messages? How can you retrieve all your old messages/conversations when you install the app on a new device? Don't they come from WhatsApp servers? Just curious, not doubting that you are actually an ex-WhatsApp employee.
