Blank dashboard on Android companion app until a change prompts for refresh

When starting the Android companion app (v2025.1.2-full) on a Huawei tablet, one of my dashboards comes up blank, i.e. with just the blue bar with the ‘Home’ title and the beefburger and kebab menus.

It’s a simple dashboard but it uses card-mod to increase the size of the fonts. The same dashboard works fine from the iPhone companion app and on a browser on PC & Mac, and all other dashboards work fine on this tablet.

If I change anything on this dashboard using another device, the app asks whether I want to refresh the dashboard, and if I choose ‘Yes’ it displays just fine, until the app is closed and reopened. I can’t find a way to get the app to refresh the page by itself.

If I (as the Owner) log onto the app on this tablet, the dashboard works fine. But if any user set up as an Administrator user or a regular User logs in, it doesn’t work.

Any ideas?
