I have recently updated the SC2 on my Schuberth E2 to the new, current firmware, V2.4. Since then I have trouble connecting to others using the mesh. The bluetooth connection with others works perfectly fine. But when I'm using the mesh - either in group mode or the open mesh - there is no usable connection. Either I can hear others and they can't hear me or the other way round or not at all, it is hard to reproduce. I did reset the mesh multiple times, also restarted the unit multiple times. Activating the mesh trhough the remote or the app makes no difference, either. The units I've tried this with are all on Mesh 3.0 and most are on current firmware, so that wouldn't (and frankly shouldn't) be an issue either. Is there an option to downgrade if this isn't resolvable any other way?
