Hi,
The BubbleUPnP and BubbleUPnP License apps both share the same user id (to be able to communicate as a single app).
Most apps do not use this obscure feature of Android (for app developers).
This share id sometimes confuses the system that sees both apps as the same app, for reporting data and/or battery usage.
You can be assured that the license app does not use data and that the value reported if for BubbleUPnP only.
