Not yet. I barely just finished transitioning my social bubble to Signal and I still get major pushback, because Signal is a bit paranoid, (in their words) which comes at a price of convenience. (for instance syncing across devices. or downloading files),

I do have SimpleX in my phone and will try to use it whenever possible. but I cannot push my friends and family to use it.

At this moment I am still offloading people from Messenger and Whatsapp. Barely anybody outside of my social bubble even knows Signal, literally nobody knows SimpleX.
