I have Whatsapp, messenger, signal, phone messages and mail and telegram, and so on. I know many of us do have the same problem and usually avoid getting new apps to communicate.
I feel like we are being played off by the communicator's providers, or else, how would you explain there is no single solution that will allow us to aggregate all messages and redirect immediately from the main interface to the given app.
I wish somebody would build something like that, it would simplify everything and we would not have to get rid of already existing solutions just help them cooperate to present us with a seamless experience no matter whose communicator it is.
