I don't know if this is related to this already existing post: https://discussions.agilebits.com/discussion/82953/secondary-account-with-own-password-doesnt-unlock-anymore
For testing I have added an additional family account (1Password.eu) to my already existing 1Password.com account. The initial master password to unlock the extension is the MP of the .com account. When I want to access the .eu account, no vaults from that are displayed.
I then go into the settings of the extension, it says that the .eu account was locked. After unlocking it (or the extension pretending to unlock it) I still don't see any .eu vaults. Going back to the settings, the vault is still locked.
