Describe the issue you are experiencing

Immediately after updating to Core 2025.12.0, one of my non-admin users reported being unable to access any subview on their home dashboard, from the iOS companion app.

On subsequent refreshes of the app, the navigation link from the home dashboard either shows up as unclickable, or may be clicked but it just refreshes the home dashboard rather than navigate to the subview.

Immediately after updating to Core 2025.12.0, one of my non-admin users reported being unable to access any subviews on their home dashboard, from the iOS companion app. This used to work fine.

I confirmed this was happening, updated their app to the latest version, restarted the app and it was still happening. my own iOS device logged in with an admin account could access the subview.

I changed their HA User profile to an admin, refreshed their app, and they were immediately able to access the subview from that point on.

Describe the behavior you expected

Clicking a navigation link to a subview from the home dashboard should load the subview.

Steps to reproduce the issue

1. Update to Core 2025.12
