Stages SB 20 bike no power reading, the watts always remain at 0 watts.

Since updating to version 7.0.6, the watts always remain at 0 watts, while the app shows, that the bike has been fully connected to the app. As the stages bike is running with the stages bike app properly, the problem must be with fulgaz. The problem occurs when using the fulgaz app via windows with my computer as well as using the app via iphone.
