I created a team account, went to Settings, changed some settings the Appearance tab, and hit the "Set Team Default" button. The page appeared to reload. Then I invited another team member, they clicked the link in the email, they set a password, and got their account created. But the new user simply did not receive the default settings.
I tried this with multiple new users, and I tried setting the team default from both Firefox 135 and Chrome 133 (both on Mac).
if the new user immediately just starts using Kagi after creating their account, they do not get the default appearance settings. If they start customizing, the default appearance settings are not the defaults when it asks users to select e.g. "Show URL Favicons". And if users click "Skip customization", the defaults are still not used.
