Beta 6 allows multiple vaults, BUT ONLY 1 VAULT PER SYNC ACCOUNT. Sigh - that is still limiting.
I would like to have 2 vaults in my family's sync drive: a vault for the whole family (including teens, for common accounts like Netflix, etc.) and a vault for parents only (for bank accounts, etc.). It makes sense to have them both on the same sync account, but Beta 6 can't do this.
