For some reason, I cannot get my Iphone to stream into my hearing aid (which I could until recently). I now have a SE Iphone and my hearing aid is a Resound Quatro8/Preza8 from Costco. I had been using the Resound Smart app. When I looked at the Resound web site, it says use the Smart 3D app. When I click on this, it says to "Open" which I click on. While my Iphone says that they are paired, the streaming does not occur. Any suggestions?
