Behavior: your app is connected to your pedal and working fine. You click on music and start a song. Within a couple of seconds, the app shows Not Connected and you cannot control the pedal even though rhe music continues to play. You have to shut the app down and start again.
After lots of testing, I have confirmed that this is a bug that happens right as the song starts and the app tries the "tone match" thing. If you can get the song to start without the disconnecting, you won't have the problem again until the next time you start the app. Sometimes it is fine and sometimes it fails everytime you play a song.
Here is one work around I have found to work. After your start your app, prepare to start a song. Click on the song you want, then as the app switches to the tone matching screen AS QUICK AS YOU CAN click back to the music library so that the app does not have the time to try and pull down the matching tones.
If you are successful, the song will play and the pedal will remain connected. For the rest of your session, you can use the app like normal, including the tone matching function.
You will need to repeat the next time you start everything again.
