4 months and app will only work with one aid or the other. Phonak says they not linked AudiNoHelpolojist says they are linked and what shecshows in Phonak Target software proves they are linked. Everytime I run the apps and start the pairing it finds both aids, but I cannot select them both like what is in instructions. I can only select one or the other. No one wants to help Update 2/15/22: Both aids are fitted together, both aids are brand new Audeo 50 312. Audiologist confirmed they are linked. They Aids are incompatible with each other? Why as it makes no sense I opened a case today as requested in link, but previous phone calls to my Phonak was unhelpful, they just keep deferring me back to an Audiologist that obviously don't know why either. This should NOT be this hard and having the Audiologist may be the problem. What the true cause this is incredibly expensive shameful product that Phonak does NOT support. I would have been better off never knowing about the app.
