I'm almost sure there was an information about battery level in My Devices on WWW some time ago.
Now it is available only in the mobile app.
I can see it is available in response for network request:
with payload: action=getbyaccountid&enrich=t&appname=hmw&apppfm=web&appliver=8da5488
So technically it is available, but it is not visible in User Interface.
Is there any plan to provide this information as it was before on WWW?
