As a long-time, very satisfied Enpass user, I'd like to echo the sentiments here. To be clear: I'm not upset that you made a major upgrade to V6, I'm upset HOW you did it.
Personally, I am tech savvy, so I was able to help myself and my partner to upgrade to V6. However, my partner had NO CHANCE at all to upgrade herself and had already started to panic (passwords missing, devices not syncing), when she asked for help. In short: the upgrade experience was catastrophic.
1. Because I loosely followed the beta program for V6, I remembered reading that V6 vaults aren't compatible with V5 and that the upgrade from V5 to V6 is a "one-way" operation with no backward compatibility to V5. I thought that was a beta-issue only and would be solved in the release. That incompatibility caused my and my partner's devices to literally break apart, because sync just stopped. No message, no error, no warning, no instructions, no announcements.
In our case, my partner lost a few passwords during the upgrade and broke sync between her devices. She had added new passwords to her Android V5 over the last couple of days. Then the upgrade automagically happened through Google Play. When she opened the new version, the passwords were imported to V6, breaking backward compat with V5 still on our Windows devices (no auto-upgrade on Windows!). So when she opened Enpass V5 on Windows, the new passwords were missing, because they didn't get moved to V6 on Windows yet. So as far as she could see, passwords were inconsistent at best or lost at worst.
2. We use Windows 10 Pro, Windows 10 Mobile and Android Oreo and Pie in our household. The upgrade experience was different for each platform. I realize you don't control the platforms, but could you at least have provided some clear upgrade guidance for each platform? Android upgraded itself, Windows 10 Pro didn't and had to upgraded/migrated manually, Windows 10 Mobile … just ended without comment.
3. At no time were we made aware of a coming upgrade and/or its consequences - much less an opt out. Microsoft is better at this, and that's saying something!
4. There is no obvious way to roll-back and recover from a failed upgrade. Really?! That is essential! Again, even Microsoft handles their Windows feature upgrades better - the roll-back actually works. If something goes wrong, users MUST be able to roll back.
Do you realize that some people have access to their ENTIRE DIGITAL LIVES stored in Enpass? Breaking that could literally ruin someone. Managing passwords and access is more critical than managing data - you have a bigger responsibility than Microsoft or Amazon, who run the world's cloud services.
What saved us was that we had all kinds of different platforms and each one failed differently, which luckily meant that at least one Enpass still worked, in order to get at our master passwords.
PLEASE DONT DO THAT AGAIN.
