TouchControl - great potential, still needs work

The interface is well thought out and is intuitive. The volume control and bass/treble balance controls function well as does the means to switch between hearing aid programs. The mute toggle button will mute both right and left hearing aids (puts them in standby mode) but does not reactivate them. To do that I must remove the right hearing aid and open/close the battery compartment (turns hearing aids off and on again). The battery strength indicator only works on my right hearing aid. I contacted the apps "help" people who said those functions should be working and advised me to contact my hearing professional. I will update after doing that.
