To preface, this happened on both of my machines so I'm escalating rather than excusing as one-off madness.
I'm a long-time user of the standalone Mac and iOS versions, and also of the Business/Teams version which happily worked alongside each other. I got a Family subscription the other day, migrated my local vault, and was immediately locked out of the app on my machine with password rejections at Master password entry, despite it working fine on the site.
I totally nuked the install on that machine, reinstalled, logged in to both accounts and it was fine after that point (though that's not exactly a fun process), but now that it's doing the exact same thing on my other machine, I'd rather see if there's a way to fix it and hopefully make sure other users don't get hosed in the same way.
Please advise on how to proceed.
