Disappointed with Proton Pass.

Great potential, but from time it doesn't remember my PIN code (and I'll never remember my master password, so have to keep it in another password app), won't let me type in the master password textbox at all (nor paste), then I logout to try again and it just hangs. Not ready for prime time, sadly. But I'm willing to wait because its email aliasing (integrated with login) has value to me.
