Sensivity settings, turning off voice, notification and connectivity problems

Hi, I tested the app and I don't like below problems:

• setting the sensitivity, I have no idea how to set these bars. why are the input values not used?
• no possibility to turn off e.g. sound recording
• I have an orbot and I couldn't understand what a "service address" is. Do I need to set up some service on the computer? wouldn't it be possible to just stream from smarthpone's IP and log in with a password?
• I don't understand why I have to insert a second sim to get notifications. Couldn't I do it with my own number?
• my app hangs quite randomly, e.g. browsing logs, samsung j4+ Cheers
