I haven't been on the forum in a while but this is about tags again:
The 1Password Online Access thing has no nested tags on the sidebar, Instead there is slashes between my tags e.g. 1PasswordTag/1PasswordTag2 instead of nesting.
1Password Version: my.1password.com
Extension Version: No idea
OS Version: Windows 10
Sync Type: 1Passsword Membership
