iPod 15.4 update

App will not stay connected to hearing aids since Apple updated iPod iOS to 15.4. It connects but after a while it loses connection and has to be reconnected. The hearing aids stay connected to iPad as normal. Works fine on iPhone 12 since update.

Thank you for your assistance but I am afraid your advice didn’t appear to help, however I have since downloaded iOS 15.4.1 update and this has fixed the problem. The hearing aids are great and really help with my hearing problems. The app is now great again also.

Good features

I have been using this app and resound HA for quite a while now, the features on the app are second to non ( I have road tested others), I use it with the tv streamer and the Bluetooth phone streamer for works phone and of course the mobile iPhone connection,
My only gripe is the connection time, if I’m streaming tv sound for example and someone wants to talk to me starting up the app (which is running) in the background takes 15-30 seconds which doesn’t sound a lot but it’s an age when you are trying to join in a conversation, or make an adjustment in a restaurant environment, please fix this on an otherwise really good app.

I have just got new aids-Resound One rechargeable. I previously had Linx2. I’ve always had issues with the apps but the 3D one is even more glitchy than the previous version. As others have said- random beeps and changes in volume/sound quality. The most annoying thing now is that the aids don’t keep the connection with my phone or tv. So I have to put one or both ( it’s not consistent) in the charging case, take them out and try again to connect. When everything works the system is ok and I like to use my Apple Watch too- but “there is a problem with the connection”appears far too often. Makes me wonder where all the money goes- probably not in app development! Please do something about this- it’s so irritating!
