Icons not displaying on Android App



I am using a Raspberry Pi to remotely monitor fire detection systems, all the inputs are digital (either on or off). Each of the inputs has been assigned an icon which is the most relevant one to the input it is monitoring.

However, on the Android App, all I get is a 0 or 1 - no fancy icons. When I open the settings for the input, it shows that it is set to icon, and lists the relevant icon, but this is all I see:

Can anyone suggest something to try to make my app screen look as lovely as my web screen please?




More app customization is on the road map, but unfortunately there is nothing that you can do today.
