We’ve been on simplex for a few months, I like it quite a bit. We made diff accounts for each device and added them all to a group.
Notifications arrive reliably on graphene (no google services), and KDE connect.
I don’t love the desktop client and wish I could change text size and scaling. I was able to message the dev about it in simplex and got replies which was cool
