We use 1Password 7 on all of our devices without issue, except that my iPhone X doesn't accept the new master password used on the other devices (Mac, PC, iPad Pro) - it requires the old master password we used before moving to 1Password 7. I checked 1Password Settings to see if there was an old vault on the iPhone X. I see "Private", "Shared Vault", and "Shared" under my shared family heading. But I also see a heading of "On Dropbox", with a vault listed under it called "Primary". I'm guessing this is my problem and that I should delete the vault on Dropbox, but I want to confirm that this is what I should do or if you have other recommendations to troubleshoot the issue.
