The way the withings app works is that you add a withings ‘user’ each withings user consists of all the stats for a ‘user’, wights, temp, blood pressure and their sleep map.
The problem with the app, oddly is you can only be connected to one account if you try and add the second it will just try add devices from the first.
I imagine that you try and add the second sleeping mat to the same user, but it does kill a lot of the uses of the actual withings mobile app.
I put in a support ticket for broken icons last year, but it still hasnt been updated, I dont think this is a high priority app.
That all said, the sleeping mat is perhaps my most useful smart item in my house.
