I noticed that 1.2.7 hasn't been muting the V1 properly for me (I don't use the audio in the app). I updated to 1.2.8 today and same thing. I've ran JBV1 for several months, and this is somewhat new. I recently noticed it (it had worked great for months), and had a chance to troubleshoot. I can't guarantee that the issue didn't happen in a version before 1.2.7; I'm just not sure. Symptoms: 1. I had an audible alert from the V1, mute lever all the way down (and set to respect the mute lever), but the visual indicator was that it was locked out, and the speaker icon wasn't big, showing the app thinks it muted it.. 2. This was also while stopped, with silent ride activated. I also ran into some non-locked out signals during silent ride, and those also weren't muted (but the screen indicated silent ride was activated, and no big speaker icon) 3. When not locked out and not silent ride, I hit the big speaker icon to mute, and it indicated that it thinks it muted it, but no mute. 4. The physical button on the V1 and concealed display are working as always. All indications are that the app thinks it muted the V1, but it didn't. Thoughts?
