UPDATE:
Just updated the app to version 3.0.3 and F…I…N…A…L…L…Y it works as it should so far. I created a Custom Program and it has been holding for about an hour or so of on and off the phone and App.
Maybe I will test turning back on some of the notification sounds to see if that has any effect. They told us we had to turn them all off because that was making the programs switch back to Automatic. What a crock.
With regard to my issue 2. I was able to keep the phone from ringing in my ear by disconnecting Bluetooth for just the R-KS hearing aid in Bluetooth settings. You just have to do it everyday when they turn on and connect to your phone.
Update 2:
I have had a couple of notification sounds turned on and it has no effect on the app. Still locked in on my Custom program after a couple of hours.
