Hello. I have a very similar problem... Never had any problems for years but recently has an issue where pin code cannot be used to re-open Enpass; it keeps saying my pin is invalid - but I have the correct pin for sure... After 2 attempts, it prompts for the master password. This is a pain as my master password is complicated. I used to re-open Enpass with my pin at least a dozen times per day and I've been doing that for years... Now that I have to enter the master pw, it's really annoying.
If I select "Lock" within Enpass, I can successfully re-open it with my pin - my pin is correct.
It's really when Enpass locks by itself and computer goes to sleep that the pin no longer works.
Any idea?
