More often than not gently heating the tip of the pen with a lighter will revitalise it. It’s worth a shot before throwing it out.

That’s sadly where it’s at. I’ve been lucky and managed to convince most of my friends to give Signal a go and in the end we stuck with it. But we’re all technically minded people so YMMV.

If you’re in the GNOME ecosystem, you could give Authenticator a shot. It’s worked quite well for me so far.
