I see there is a new account switching feature.
How do I separate my existing families account from my business account?
I don’t think account switching is supported for the Web Vault. However, in the Desktop app and browser extensions, you click on the profile button in the top right corner, then select “Add Account”.
ok, but my family plan is inlucded with my business subscription, so its all under the same login.
That seems odd. These are the instructions for how to redeem a free Family plan that is sponsored by an Enterprise plan; the instructions explicitly state that when setting up an account to use for your Family plan, you should not use the same email username that you have used for your organization account. Did you follow those instructions when setting up your Family plan?
