User Permissions don't seem to work

I set up a private page for approved users. The permissions I set don't seem to work (except for site.login). I can't get it to work with groups, either. Its header looks like this:
Page Header

title: Approved
access:
    site.approved: true

The test user I have is set up as follows:
user .yaml

email: [...]
access:
  site:
    login: true
    approved: true
hashed_password: [...]

For some reason, I'm still getting an Access Denied page. The page prompts me to log in when I'm not, though.

Setting up user groups like this doesn't work either:
groups.yaml

approved:
  groupname: approved
  icon: users
  readableName: 'Approved Users'
  description: 'The group of approved users'
  access:
    site:
      approved: true

User .yaml

email: [...]
access:
    site:
      login: 'true'
groups:
  - approved
hashed_password: [...]

I'm still getting an Access Denied with this user. Am I doing something wrong? It used to work like this.

Solved: Seems like I have to log out and in again...
