I'm an Enpass Pro Lifetime user too.
First I understood that these 2 new features (breach and 2FA) are an addon service where I have to pay another ~20€ p.a. -> OK a laborious service with an extra (recurring) fee.
BUT: now I see a new license "Premium" and the "Individual Plan" costs 21,49€ p.a.!? And that includes "Pro plus the 2 new Features". That's nearly the same like my Upgrade.
I think this is a big bug in the license model and makes it intransparent and unfair for all old user.
