Default JB4 app not showing data anymore - 10-09-2020, 03:10 PM

I installed a Bluetooth kit yesterday on my JB4 by a professional tune shop everything was working fine I suppose but suddenly no live data was showing. The only one working was water temperature and a false transmission temperature (-17°C). Also the log was only showing flat bars

What could’ve caused that?

Before the incident I was normally driving in S+ and changing a couple times from map 0 to 1 to see the difference.
