No, that's not true. And not a lot of help, frankly. If you try encrypt a new note when you have encrypted previous notes,, and mess up the encryption phrase, you get a box stating "The encryption phrase you entered is different from the one you previously used to encrypt note content" It does give you the option to use a different passphrase If you actually choose that option it asks for a new hint as well. So let's work on the principle I'd not be asking the question if I'd be daft enough to deliberately select the option highlighted "NOT RECOMMENDED" and jump through those hoops given they're a big red warning thatI I'd be right on the way to ***** this up. (You think I'd mistype the same passphrase in that box twice, and use the same password hint as I'm used to? Really? Occam's Razor is starting to apply here!) So - let's work on my initial thought - that I have a corrupted encrypted note. How does that make you feel?
