Broken

Awesome app and tunes but the recent update that was supposed to fix connectivity drops did the opposite. If it connects, its only for a few seconds then drops for a few min before trying to connect again. The short time it was connected for 20 min, dashboard didnt work at all.

Love this app

Bootmod3 is so easy to use anyone can do and the new update is super fast and responsive I just wish you guys would rewrite the names of what the berbals was called when trying to put it louder or more quiet cause it’s kinda hard to understand what does what but all in all great app and tune
