Thanks. Yes I did. Even running a private browser window. Did sadly not saved the problem.
I love DD! I want to make this dashboard accessible to other family members (not admins). Their access must be limited to DD and all other dashboards and sidebars must be hidden for them. HACS kiosk (https://www.youtube.com/watch?v=G3lT4zgjER8) does not work because DD root yaml code editing is not possible. How can should I configure HA such that only a DD control panel is visible for non-admins? Thanks!
