Hey @jayg, great to hear that this worked for you!
If you'd like to make extra sure that your data is in good shape and always available to you, I'd recommend signing into 1Password.com, taking a quick look to make sure you see all your expected items there, and then saving a copy of your Emergency Kit and writing your account password on it. With that in place, you know you'll always have access to your data, no matter what.
With that said, we really haven't heard any horror stories about 1Password 8 Nightly borking (😆) anyone's data, but it is still pre-Stable
and it's always good to have a plan anyway, you know?

And thanks to DenalB for the helpful answer here! Forever on the cutting edge. 😄
